patch: reapply path limit This was originally applied added in commit eac1b67 (ui-patch: Apply path limit to generated patch, 2010-06-10) but the ability to limit patches to particular paths was lost in commit 455b598 (ui-patch.c: Use log_tree_commit() to generate diffs, 2013-08-20). The new output is slightly different from the original because Git's diff infrastructure doesn't give us a way to insert an annotation immediately after the "---" separator, so the commit has moved below the diff stat.
