I would like to agree, but the problem is that there are currently
only few things that produce an error with compctl and I wouldn't like 
to use an unused option character for something is behaves more like
`+' (separating option lists) than like an option.

Yes, sorry, little confusion in my internal hash tables...

Maybe I should have been more precise here. I didn't meant that the
user would have to worry about giving weights to the compctl options
(I can't even think of a compctl-syntax for that). What I meant was
that the user may say for different option lists (those separated by
inclusive-or's) that the results of this lists should be sorted
separately. Of course that could be changed to: not sorted at all, and 
especially not sorted into the whole list.
The completion code would derive the weights from this automatically.
