Yes, it's a good one.
It contains:
* MATCH ?? ^^\/([^-]|-[^-])+
which I think does the same as
* MATCH ?? ^^\/.*[^-]
Is there a special reason for your (or Bart's) approach?
There is a difference, Ruud; your simplification can match a string with
two or more successive hyphens, as long as there is at least one
non-hyphen at the end. Sean's (or Bart's) cannot match a string with
two adjacent hyphens. I think ^^\/(-?[^-])+ is equivalent to it, but
there are always those considerations of the form that's most efficient
for procmail to parse, and I never know how to determine that.
