Yes, i was aware of that.  The problem is that some programs would not
continue parsing `-c...' as a possible option, while some would.  I
think I would call such programs `well-behaved'.

I also seem to remember that we discussed this many months ago, but
don't know what we said about all this then.

It seems doable to add another option to _arguments telling it that even
after such an option other options should be completed.  Would that have
to include options described as `-c-:...'?  Or do we even have to allow
specifying that on a per-option basis, i.e. add yet another special
character that may be given after the option name to say that there is
an argument to be completed directly after the option, but other options
might come, too?
