I was fearing problems with the ignore-parents style, but all the
things I tried worked as before.

Yep, I think. We should probably make that depend on another style
anyway (one that default to true -- ignore-same or something better).

Only what I think you are thinking about anyway: making some of the
new values modifiers, e.g.:

  zstyle '...' ignore-line other quote

where `quote' is a modifier `working on' `other'.

Damn, I hoped you had an idea, ready to be implemented ;-)

I'm not sure, either. Probably the cleanest solution would be to give
_description an option to tell it which ignore-line value should be
used as the default. But that would need changes in every utility
function calling _description to pass down that option, which isn't 
nice.

And using a completion-system-global parameter to pass this
information to _description isn't clean either.

Hm.
