copy/move --from-anywhere --to remote
Implementation was simple because it's equivilant to
--from=foo --to remote for each other remote, followed by
--to remote when there's a local copy.
(Or, in the edge case of --from-anywhere --to=here,
it's the same as --to=here.)
Note that, when the local repo does not have a copy,
fromToPerform gets it from a remote, sends it to the destination,
and drops the local copy. Another call to that for a second remote
will notice that the dest now has a copy, and simply drop from the
second remote, avoiding a second transfer.
Also note that, when numcopies doesn't allow dropping it from
everywhere, it will drop it from the cheapest remotes first
(maybe not ideal) up to more expensive remotes, and finally from the local
repo. So the local repo will generally end up holding a copy. Maybe not
ideal in all cases either, but it seems no worse to do that than to end up
with a copy undropped from a remote.
And I'm not entirely happy with the output, eg:
copy bigfile (from r3...) ok
copy bigfile ok
That makes sense if you think of the second line as being
the same as what is output by `git-annex copy bigfile --to bar`,
but it's less clear in this context. Maybe add "(from here...)"?
Also the --json output doesn't have a machine-readable field for
the "from" uuid, and maybe it should?

fix --from overriding annex-ignore
Make git-annex get/copy/move --from foo override configuration of
remote.foo.annex-ignore, as documented.
This already worked for remotes supporting hasKeyCheap. For others though,
git-annex copy --from foo would silently not do anything, while
git-annex copy --to foo would use the annex-ignored remote.
Also improved the annex-ignore docs, to reflect that `git-annex get`
without --from will skip using annex-ignored remotes, for example.

dial back addition, but keep it
It's a semi-common point of confusion that numcopies is not something
these commands go out and copy files around specifically to satisfy,
without further configuration in preferred content. So this is a good
addition, but it also seemed too long and too specific to the user's
particular situation.

Add note to 'satisfy' manpage about it not satisfying numcopies and how to set it up to pass files between remotes that are not present locally.
I got bitten several times in the past by the fact that local preferred
content expressions are not violated (even temporarily) in order to
satisfy numcopies or other remotes' preferred content expressions.
Mostly in the form of the local repo not allowing arbitrary files in
(e.g. because it's set to only want `present` files). This note I add
here explains how to get out of this situation with
`approxlackingcopies=1`.
It might be too specific for this manpage, but I didn't find a better
place to put it.

improve attribution armoring
Split out an author parameter, will make it easier to add authors and
reads better.
Got rid of the function without the copyright year, because an adversary
could have mechanically changed the function with a copyright year to
the one without, and so bypassed the protection of LLM copyright
year hallucination.

make my authorship explicit in the code
This is intended to guard against LLM code theft, which is the current
bubble technology de jour.
Note that authorJoeyHess' with a year older than the year I began
developing git-annex will behave badly, by intention. Eg, it will spin
and eventually crash.
This is not the first anti-LLM protection in git-annex. For example see 9562da790fece82d6dfa756b571c67d0fdf57468. That method, while much harder
for an adversary to detect and remove, also complicates code somewhat
significantly, and needs extensions to be enabled. There are also
probably significantly fewer ways to implement that method in Haskell.
This new approach, by contrast, will be easy to add throughout the code
base, with very little effort, and without complicating reading or
maintaining it any more than noticing that yes, I am the author of this
code.
An adversary could of course remove all calls to these functions
before feeding code into their LLM-based laundry facility. I think this
would need to be done manually, or with the help of some fairly advanced
Haskell parsing though. In some cases, authorJoeyHess needs to be
removed, while in other places it needs to be replaced with a value.
Also a monadic use of authorJoeyHess' may involve other added monadic
machinery which would need to be eliminated to keep the code compiling.
Alternatively, an adversary could replace my name with something
innocuous. This would be clear intent to remove author attribution
from my code, even more than running it through an LLM laundry is.
If you work for a large company that is laundering my code through an
LLM, please do us a favor and use your immense privilege to quit and go
do something socially beneficial. I will not explain further
developments of this code in such detail, and you have better things to
do than playing cat and mouse with me as I explore directions such as
extending this approach to the type level.

Make git-annex copy --from --to --fast actually fast
Eg when the destination is logged as containing a file, skip
actively checking that it does contain it.
Note that --fast does not prevent other verifications of content
location that are done in a copy --from --to. Perhaps it could, but this
change will already avoid the real unnecessary work of operating on
files that are already in the remote.
And avoiding other verifications
might cause it to fail if the location log thinks that --to does not
contain the content but does. Such complications with `git-annex copy
--to remote --fast` led to commit d006586cd0b706c9cc92b2747b2ba3487f52c04a
which added a note that gets displayed when that fails, mentioning it
might be due to --fast being enabled.
copy --from --to is already complicated enough without needing to worry
about such edge cases, so continuing to doing some verification of
content location after the initial --fast filtering seems ok.

git-annex log --gnuplot
The gnuplot output is pretty good, but could still be improved with:
* more colors (repeating colors is confusing with a lot of repos)
* better positioning of the legend, making the plot wider and moving it

git-annex log --received modifier option
Only counting received and not dropped makes this show the bandwidth of
data coming into the repository, although only in a sense. Since
git-annex branch updates only happen at the end of a command, and we
don't know when a command started, it's only an approximation of the
actual bandwidth. (A previous git-annex branch update made have
happened in a different repository.)
It would be possible to also add a --dropped option, but I don't know
how useful that would be?

guard against wrong timestamps in git log
For example, my sound repo has in the git-annex branch a commit from
2036, which is followed by one from 2034, in amoung commits from 2013.
Clearly there was a problem with the clock.
Since git log --date-order has a behavior of
"Show no parents before all of its children are shown", the data still
gets processed ok. The future timestamp just prevented displaying data
after that commit. It seems better, when the clock was wrong, to display
a wrong date, and then return to right dates.
It would be nice to filter out the wrong dates from display entirely,
but that seems it would need to buffer the whole output. This command is
too slow to buffer it all before displaying anything, and anyway this
kind of problem is probably rare.

treat dead repos as 0 size
With this, git annex log --totalsizes can be compared with
git-annex info's "combined annex size of all repositories"
to double-check it works correctly.
In my sound repo, the two match.
In my big repo, the two report slightly different sizes,
with the former being 1.3 gb smaller than the latter.
I don't know the reason for this disreprency. Given the 30+tb size of
the repo, it's a small difference.
It seems possible that a bug in an old version of git-annex could
explain it. Eg, if an old git-annex lost a line when updating trust.log
or a location log in a merge, git-annex info would see only what it
replaced it with, while git-annex log will see the previous value as
well.
