Subject: Work around git bug in handling of relative path to GIT_INDEX_FILE
 when in a subdirectory of the repository.

This affected git annex view. It turns out that some other places
that use GIT_INDEX_FILE were already working around the bug. I removed the
workaround from Annex.Branch since the new workaround will do.
