unused, dropunused: Now work in bare repositories.

Turned out I had already done all the work needed to support this when
unused started checking all branches.

-Known to work ok:
+It took a while, but bare repositories are now supported exactly as well
+as non-bare repositories. Except for these caveats:
 
-* `git annex move --to` and `--from`, when pointed at a bare repository.
-* `git annex copy` ditto.
-* `git annex drop` can check that a bare repository has a copy of data
-  that is being dropped.
-* `git annex get` can transfer data from a bare repository.
-* Most other stuff (ie, init, describe, trust, etc.)
-
-There are a few caveats to keep in mind when using bare repositories:
-
-* A few subcommands, like `unused` cannot be run in a bare repository.
-  Those subcommands will refuse to do anything.
+* `git annex fsck` works in a bare repository, but does not display
+  warnings about insufficient
+  [[copies]]. To get those warnings, just run it in one of the non-bare
+  checkouts.
+* `git annex unused` in a bare repository only knows about keys used in
+  branches that have been pushed to the bare repository. So use it with care..
