safer git sha object filename
Rather than use the filename provided by INPUT, which could come from user
input, and so could be something that looks like a dashed parameter,
use a .git/object/<sha> filename.
This avoids user input passing through INPUT and back out, with the file
path then passed to a command, which could do something unexpected with
a dashed parameter, or other special parameter.
Added a note in the design about being careful of passing user input to
commands. They still have to be careful of that in general, just not in

compute remote: get input files from other remotes
This needed some refactoring to avoid cycles, since Remote.Compute
cannot import Remote.List. Instead, it uses Annex.remotes. Which must be
populated by something else, but we know it has been, because something
is using Remote.Compute, which it must have found in the remote list,
which populates that.
In Remote.Compute, keyPossibilities' is called with all loggedLocations,
without the trustExclude DeadTrusted that keyLocations does. There is
another cycle there. This may be a problem if a dead repository is still
a remote.
This is missing cycle prevention, and it's certianly possible to make 2
files in the compute remote co-depend on one-another. Hopefully not in a
real world situation, but it an attacker could certainly do it. Cycle
prevention will need to be added to this.

Another reason would be a user who has installed a compute program by

pulled in by some dependency. That user doesn't necessarily want that

a symlink that is checked into git does not get followed. This is important
for security, because following a symlink and adding the content to the

the repository.
Instead, the behavior with a symlink is to run the computation on the
symlink target. This may turn out to be confusing, and it might be worth
addcomputed checking if the file in git is a symlink and erroring out.
Or it could follow symlinks as long as the destination is a file in the

useful if the program comunicates with something less trusted than it,
