[PATCH] _git: Apply matchspecs to filename completion such as 'git log f/b<TAB>' → 'foo/bar.txt's

[Daniel Shahaf <d.s@xxxxxxxxxxxxxxxxxx>]

This patch makes 'git log S/e<TAB>' expand to Src/exec.c.  The incumbent
code would run 'git ls-tree S/' and find no matches.
---
I realize this makes the output size O(tree) (index lookups, not
readdir()s).  If this turns out to be a problem for larger repositories,
I assume either the listing could be made smarter (list the tree to a more
limited depth or breadth) or the result cached.
