$tow(<word> <word list>)

• If the <word> argument is omitted this function returns the empty string.
• If <word> is not found in <pattern list>, this function returns the empty string.
• Otherwise, the function behaves “as if” the following had been performed:
  <val> = findw(<word> <word list>) + 1
  <function_return> = leftw(<val> <word/pattern list>)
• Remember that <word list> is a list of words.

Portion of <word list> before and including a literally matching word.

$tow(foobar one two foobar my shoe)    returns "one two foobar"
$tow(booya one two foobar my shoe)     returns ""  (empty string)

This function first appeared in “plus 2” (post-ircII, pre-EPIC)
