Simpler Section Numbers

You simplified it a lot by dropping $maxdigs.

It's a fair cop, but society's to blame.

I appreciate your final no-hash sprintf approach, but modifying temp values in a grep gives me the screaming heebie-jeebies, you know what I mean? I'd much rather use map for that sort of thing. But I can't argue with the fact that it works.... And my Rule #0 is, ``Anything that works is better than anything that doesn't.''

Actually I wrote it as map first and, of course, it didn't work because s// doesn't return the modified string. Breaking the unwritten rule of grep seemed slicker than:

map {s/.../.../ge; $_}

which still hides side-effects inside map or:

map {(my $x= $_)=~s/.../.../ge; $x}

which just, well, isn't slick. :)
