The only other solution I've thought of would be to defer all tag/label
loops until the very end after all matches are added. It'd need to
track the path of added matches building up a list of associated tags.
It would allow the mixed label/tag tag-orders like the example above
but be less efficient because unwanted matches would be generated.

I think I prefer my first idea which also has the advantage of being
closer to the current system. I don't think separate tag and label
ordering would matter much. I've still got some lines of thought I want
to follow though.

If the tags dependence on funcstack to track nested tags loops goes, we
may need to act on a tag loop exiting. Currently, we break out of the
loops with `(( ret )) || break'. Can't that be done with a
compstate[nmatches] test in _tags - I'd prefer if we didn't have to set
and test $ret there anyway.

Ah, that explains.

Okay, but those _wanted calls use a different tag. Labels setup for the
urls tag might not then be handled.
