Yes, please bump #serial. Our policy is that #serial equals the number
of commits that modified that particular macro in our Git repository, so
any modification should come with a bump, regardless of whether code was
changed or not. I usually run "./set-serial.sh m4/*" once in a while to
make sure that promise holds.

Great, that sounds quite sensible. Thanks a lot for you effort!

Take care,
