I didn't write the original rule.  I just wanted to add a special
case.

No, if what you're really doing is adding a special case to a simple
rule, I think it's easier to understand than if you write a
complicated rule.

In English.  In Regexp, I think lots of people can follow the original
(not really mine) more easily.  But I don't feel strongly about it.
In fact, I could easily argue that the feature shouldn't be
implemented at all, since it's not a part of anyone's idea of how to
write ABC.

Yes.

Anyway, the whole issue seems to be moot at the moment, because the
whole patch seems to have disappeared from 2.9.20, although it was
there in CVS the day before.  This feature isn't important, but the
fix to the tempo setting is release-critical, in my opinion, so I hope
at least that part of it comes back.

I put all of my patches back, using Juergen's syntax for the lyrics
extenders, and can send the patch again if it will help anyone.
