It means that the bit that hs .- , above makes ZERO sense, because ,
comes before . in ASCII, so you can't do that range you just tried to
do.
Of course, you weren't actually trying to do a RANGE, but when you
tacked ' ,/' onto your pattern, you weren't paying attention to the
fact that - has to be at the very end, or very beginning, or (maybe?)
escaped so that EREG knows it's not a RANGE you are defining, but a
single character in the character set.
