understand adjusted view branch names
An adjusted view branch has a name like
"refs/heads/adjusted/views/master(author=_)(unlocked)", so it is a view
branch that has been converted to an adjusted branch.

Made Logs.View support such branch names. So now git-annex sync and
pre-commit handle updating metadata on commit in such a branch.

Much remains to be done to fully support adjusted view branches,
including actually applying the adjustment when updating the view branch.
