reusing repository uuid cannot result in data loss AFAIK

Avoiding such problems is one reason why git-annex does active
verification of other copies of a file when dropping.

You could argue that reusing the uuid of a trusted repository leads to
data loss, but that data loss doesn't really involve reusing the uuid,
but instead is caused by deleting a trusted repository. Using trusted
repositories without a great deal of care is a good way to blow off your
foot, of which deleting them is only the most obvious;
added some sections about that.

If reusing a repository uuid could result in data loss then I'd be on
board with making reinit run a fast fsck to update the location log, but
since it can't, I feel that is not worth forcing. Not a bad idea to run
fsck afterwards. Updated language about that.
