Thanks, and surely that is very readable.

Alternatively, I think you can just compare refname and rule until
they diverge, without doing any special casing for per-cent on the
rule side inside the loop.

If you do not find any difference, or the byte that differ is not
the per-cent at the beginning of "%.*s" on the rule side, they they
do not match.
