Automatic long options completion for --?

Automatic long options completion for --?

[Andrej Borsenkow]

Struggling with Cygwin I found myself wishing to get at least trivial
completion for arbitrary command with long options.

Is it possible to complete after -- for *any* command (of course, assuming
that no specific completion is defined)?

Of course, if this could extract help text as well ... :-)

I've been fooling around with a function to be a front-end to _use_lo
that would try to determine whether the command accepts --help and poke
_use_lo into _comps if it does.  Maybe there's some way to combine it
with Adam's completion caching layer so zsh could "learn" which commands
can be completed that way.

We had this before. Sometimes just telling us about great ideas is
enough. Sometimes we need more help and sometimes we don't feel like
implementing this ourselves ;-)

So, if you can come up with something reasonable, that is guaranteed
to never produce a wrong description but at least sometimes gives the
right one...
