Nice to see progress there!  Don’t hesitate to stop by on IRC or the
mailing list when you have questions or when in doubt, or just to share
your latest achievements.

I was going to suggest postponing this feature, but I see in the repo
you already came up with a reasonable solution (maybe not fool-proof,
because it should be possible to escape the percent character, and then
you can’t just use regexps, but it’s probably good enough.)

Thanks for the update,
