BTW: s/was/is/ - it's still there ;-)

Exactly. It doesn't hurt, but it's not needed. (Not only in the Reply-To
check.)
The only place where - has a special meaning in regexes is inside square
brackets like [a-f] which matches the letters a, b, c, d, e and f.
To make it more interesting, you can't escape - inside []. Instead you
have to add it at the beginning or the end if you want to match a -
inside [], for example [a-f-] or [-a-f] will match a, b, c, d, e, f
and - (using [a-f\-] would also allow a \).

Hmm.. Good point Adrian. I should get used to that thing
close to my keyboard... how did you call it? Mouse? :-)
