======Synopsis:======
$__chngw__(<index> <word> <word list>)

======Technical:======
   * If the <index> argument is omitted the empty string is returned.
   * If the <word> argument is omitted the empty string is returned.
   * If the <index> argument is less than 0 then <word list> is returned.
   * The return value if <word list> with the <index>th word, counting from zero, changed to <word>.
   * Remember that <word list>s are always [[what is a word|words]].

======Practical:======
If you need to change one of the words in a word list, use this function.
I originally used this function to permit changes to access levels on my
bot on the fly.

======Returns:======
<word list> with the <index>th word changed to <word>, counting from zero.

======Examples:======
$chngw(2 blah foo bar booya)          returns "foo bar blah"

======History:======
This function first appeared in "plus-2" (post-ircII, pre-EPIC)
