git-apply --reject: finishing touches.

After a failed "git am" attempt:

	git apply --reject --verbose .dotest/patch

applies hunks that are applicable and leaves *.rej files the
rejected hunks, and it reports what it is doing.  With --index,
files with a rejected hunk do not get their index entries
updated at all, so "git diff" will show the hunks that
successfully got applied.

Without --verbose to remind the user that the patch updated some
other paths cleanly, it is very easy to lose track of the status
of the working tree, so --reject implies --verbose.
