$rfilter(<word> <pattern list>)
This function lets you “filter” <pattern list> through a word, keeping all of the patterns that do not match a given word, and discarding all of the patterns that do match the given word.
If you have a list of patterns, some of which match a word (say, a nick!user@host string) and some of which don't, and you want to remove the ones that do, this function will do that.
The list of patterns from <pattern list> that do not match <word>.
This function first appeared in “plus-2” (post-ircII, pre-EPIC)
$rfilter(foobar f* *oo* a* *c) returns "a* *c" $rfilter(hello hello a* *lo*) returns "a*"
