 +======Synopsis:======
 +$__beforew__(<word> <pattern list>)
 +
 +======Technical:======
 +   * If the <word> argument is omitted this function returns the empty string.
 +   * The <pattern list> does not actually need to be a list of wildcard patterns.  A list of literal words will work just fine.
 +   * If <word> is not matched by any of the words in <pattern list>, this function returns the empty string.
 +   * Otherwise, the function behaves "as if" the following had been performed: <val> = rmatch(<word> <word/pattern list>) <function_return> = leftw(<val> <word/pattern list>)
 +   * Remember that <pattern list> is a list of [[what is a word|words]].
 +
 +======Practical:======
 +This function lets you get the part of <pattern list> that occurs BEFORE
 +the pattern that is the "best match" for <word> You can of course use
 +this function with a list of literal words.
 +
 +======Returns:======
 +The portion of <pattern list> before the pattern that is the "best match"
 +of <word> A word is always "best matched" by itself; see the help file
 +on pattern matching for more detail.
 +
 +======Examples:======
 +<file>
 +$beforew(foobar one two foobar my shoe)    returns "one two"
 +$beforew(booya one two foobar my shoe)     returns ""  (empty string)
 +$beforew(foobar o* t* f* m* s*)            returns "o* t*"
 +$beforew(booya o* t* f* m* s*)             returns ""  (empty string)
 +$beforew(foobar f* fo* foobar foo* foob*)  returns "f* fo*"
 +</file>
 +
 +======History:======
 +This function first appeared in "plus 2" (post-ircII, pre-EPIC)
