Remove GNU Readline rl_complete() prototype, for now

Browse Source 
We should add a configure option --enable-readline-compat, or sth, so
rl_complete2() (removed in this commit) becomes the new rl_complete(),
and the current rl_complete() becomes el_complete().

The current implementation of rl_complete2() was is incomplete and also
not working properly.  To eliminate any confusion on the matter this
patch removes it.  To restore functionality we should, at the very
least, merge with complete() and possibly also refactor rl_find_token()
to share code with the legacy el_find_word().
