I am happy to see we are in agreement.  I touched this in the
ending note to

	http://article.gmane.org/gmane.comp.version-control.git/26432

The only people who will get burnt by this change are the ones
with metacharacters in their pathnames, so it is relative safe
change.

I think 'git grep' pathspec code is probably the best to reuse
to convert diff-tree family.  It knows how to match globs while
traversing a tree down without descending into a subtree that
would never match, which is what we need for them.
