pre-commit: Update metadata when committing changes to annexed files within a view.
So the user can now switch to a view and then move files around within it
to manage metadata. For example, moving a file into a new directory
when in the tags=* view adds a tag to it.
Implementation is fairly efficient. One diff-index, which is no more
expensive than the first stage of a git commit, followed by possibly
some cat-file --batch traffic to find the key (when deleting a file).
Very similar to what's done in direct mode when committing. And like
direct mode when updating the WC after a merge, it has to buffer the
diff-tree values in order to make 2 passes over them.
When not in a view, pre-commit now does one extra git symbolic-ref,
which is tiny overhead.
This commit was sponsored by Andrew Eskridge.
