[PATCH 1/5] bashcompinit: remove _compgen_opt_words

[Felipe Contreras <felipe.contreras@gmail.com>]

There's already code for this[1]:

  support for the last, `word' option to compgen. Zsh's matching does a
  better job but if you need to, comment this in and use compadd -U

So either we rely on zsh's matching (compadd), or we enable this code
unconditionally so compgen works the same as in bash--and use compadd -U.

This kinds of reverts 2e25dfb[2], except that the original code:

 eval "results+=( $OPTARG )"

was wrong; it would fail if IFS is different. The new code has
'words=( ${~=1} )', which is corrent, and I transalted that to
'results+=( ${~=OPTARG} )', so there should not be any regression.

The original report for 2e25dfb[2] explained this is the desired
behavior.

 $ compgen -W 'abc abe ab a def' ab
 abc
 abe
 ab

If the code in [1] is enabled, I get _exactly_ the same result.

[1] (( $# )) && results=( "${(M)results[@]:#$1*}" )
