Prevent git-ls-files from double-expanding wildcards when an unexpanded wildcard is passed to a git-annex command like add or find.

Note that previously, `git annex find *.jpg` would find eg, foo/bar.jpg.
That was never intended or documented behavior, so I'm going to change it.
But this is potentially a behavior change if someone discovered that
behavior and relied on it despite it being accidental. Oh well.. can't make
an omlette w/o breaking some eggs.
