Ah. See? I suggested then when I first started participating in the
coloured-completion-lists discussion.

Ick. Maybe we should keep the parameter side more standard and just
use `bold:blue:white' or `bold:fg=blue:bg=white' or something. And
then add a function that uses a mini-language... err, wait, where have 
I heard that before.

I have almost given up dreaming about it, but: stuff like this always
reminds how nice it would be to generalise some of the completion-setup 
stuff to a more general package system. And then allow something like: 
`zstyle 'prompt:...:foreground' bold blue'.

...which complist currently can't do because it uses ZLS_* only for
files. But I have already asked: should we change it to allow using
pattern-capabilities for normal matches, too? The only problem I have
with that is that I would like to be able to give such specs per group 
of matches added. And that would require changes to compadd which
doesn't (and, in my opinion, shouldn't) know about complist. Hrm.

Bye
