Implement length(PWideChar) with IndexWord.
I avoided suggesting this before !670 (merged) because I thought that former length(PWideChar)
it changed to −1
might then be the only use of IndexWord
by simple programs. But as I see now, even empty application uses IndexWord
anyway, so at least this is not the reason not to use IndexWord
(maybe there were others, otherwise why is it made that way).
