All command line stuff today..
Added --want-get and --want-drop, which can be used to test preferred content settings
of a repository. For example
git annex find --in . --want-drop will list the same
git annex drop --auto would try to drop. (Also renamed
git annex content
git annex wanted.)
Finally laid to rest problems with
git annex unannex when multiple files point to the
same key. It's a lot slower, but I'll stop getting bug reports about that.
