======Synopsis:======
$__afterw__(<word> <word list>)

======Defined behaviors:======
   * __afterw__() == []
   * __afterw__(word) == []
   * __afterw__(word some list) == []
   * __afterw__(word a word list) == [list]
   * __afterw__(WORD a WoRd list) == [list]
   * For any __$x__: __afterw__(word __$x__) == __restw__(__findw__(word __$x__) __$x__)
   * The same as findw(), afterw() honors __/xdebug dword__
   * The same as findw(), all string comparisons are case insensitive
   * The same as findw(), afterw() honors your locale's collation rules

======Practical:======
  * This function returns the part of a word list that occurs after a given word.
  * If the given word is not in the word list, the empty string will be returned
  * If there are not enough parameters, the empty string will be returned

======Examples:======
<file>
$afterw(foobar one two foobar my shoe)    returns "my shoe"
$afterw(booya one two foobar my shoe)     returns ""  (empty string)
</file>

======History:======
This function first appeared in "plus 2" (post-ircII, pre-EPIC)
Long ago, this function used to do wildcard matching instead of literal string compares.
