[issue390] git diffs leave empty diffs in MQ patches

[John Levon]

New submission from John Levon <levon at movementarian.org>:

If I modify a file in a patch, qrefresh, then undo the modification, then
the file is still listed as an empty diff in the patch:

xenbld:xen.hg $ hg qnew foo
xenbld:xen.hg $ echo a >>Makefile
xenbld:xen.hg $ hg diff
diff --git a/Makefile b/Makefile
