 +======Synopsis:======
 +$__rpattern__(<word> <pattern list>)
 +
 +======Technical:======
 +   * If the <word> argument is omitted the empty string is returned.
 +   * This function returns a space separated pattern list of all of the patterns in <pattern list> that match <word>.
 +   * This is the complement to $[[rfilter]](), and the inverse of $[[pattern]]().
 +   * Double quoted words are honored, but the double quotes will be lost in the return value.
 +
 +======Practical:======
 +This function lets you "filter" <pattern list> through a word, keeping all
 +of the patterns that match a given word, and discarding all of the patterns
 +that do not match the given word.  If you have a list of patterns, some of
 +which match a word (say, a nick!user@host string) and some of which don't,
 +and you want to remove the ones that don't, this function will do that.
 +
 +======Returns:======
 +The list of patterns from <pattern list> that match <word>.
 +
 +======History:======
 +This function first appeared in "plus-2" (post-ircII, pre-EPIC)
 +
 +======Examples:======
 +<file>
 +$rpattern(foobar f* *oo* a* *c)     returns "f* *oo*"
 +$rpattern(hello hello a* *lo*)      returns "hello *lo*"
