_a2ps completion is broken

[please CC-me, I'm off the list]

Hi,

a2ps has changed its `--list=feature' output 
(somewhere between 4.10.4 and 4.12c, I don't know when)
which is used by zsh-3.1.6.pws6/Completion/User/_a2ps.

Besides this output is subject to locales so LC_ALL=C 
should be added (is there any other completion functions 
affected by this ?).  

The following patch should fix both things and still work 
with old a2ps. I would really like to know if there is an
easiest way to make these patterns matching case insensitive.
