That's what I did, but I used a new name for the old argument and the
old name for the new argument. I did so as the old name fits the new
behaviour more.

This is a backward-compatible change for indent-relative, but it does
use the new behaviour for indent-relative-maybe. Is that alright with
you?

Sure, I'll do that once the code changes are agreed upon.
