Will do so and experiment with it when I find the time for it.

Hmm looks like I have overlooked this one. I have removed it and didn't
notice anything strange.

This is definitely a good tip. I will look into this. Thanks.
I have some more questions regarding my completion attempt : my
completions don't get coloured. Where should I look to fix that ? It
would also be nice to cache completions, but that is way beyond me right
now. And is the only way to prevent calling _cc_files by using -A "-*"
arguments to _arguments function ?
Thanks for assistance.
