Re: [PATCH v2] t4129: don't fail if setgid is set in the test directory

We probably do not use "chmod g+s" manually on regular files, so I
may be being overly "correct", but shouldn't these be done only for
directories?

 test_modebits () {
-	ls -ld "$1" | sed -e 's|^\(..........\).*|\1|'
+	ls -ld "$1" | sed -e 's|^\(..........\).*|\1|' \
+			  -e 's|^\(......\)S|\1-|' -e 's|^\(......\)s|\1x|'

That is, 

			  -e 's|^\(d.....\)S|\1-|' -e 's|^\(d.....\)s|\1x|'

instead of applying the rule to any filetype.

Will queue as-is, as the distinction probably would not matter in
practice.

Thanks.
