This looks OK, since (presumably?) it guarantees a special context after
the name of the completer --- working well with the patch included in this
post. But for people to be sure they're matching the command name, they're
going to have to do things like :*:*:dvips:* anyway, and presumably most
people (probably including me) won't be that careful. Still, it's
I see this has now become just `::', which is OK if it's going to be used a
lot, something I can't really tell yet. If it isn't, the full -argument-
thing might be more consisent.

I'm so far a bit agnostic on this sort of thing. How many people are going
to go into this sort of detail to sort out groups and tags, whatever the
syntax is? Groups in particular are fairly well buried inside completion
functions (unless something's changed here, I haven't completely absorbed
everything about the latest status yet). But I'm not against control of

All this stuff sounds reasonable. Styles are good because we could, as I
mentioned (without doing anything about it :-/), put them into an
extended menu-driven compinstall, so it becomes easy to alter.

Maybe they should behave like a special completion group, with a message
above like `<Hidden Matches>', or something. It makes it all explicit.

OK by me.

We should make a complete list of the current ones (easy but dull) and see
what it looks like, then maybe we'll get ideas.

The words which come to mind are horribly generic, like `type', or
something involving `context' which will be ambiguous, even though it
describes how tags are thrown up. Unless someone has a brainwave, tag is
at least (with our current language) reasonably unambiguous.

Without actually looking, I don't think it would be hard to have a pointer
which always points to the top-level options, and let parameter access
that. In fact it *sounds* pretty trivial.

Needs checking, but can safely be left till fairly late, since it's
maddening to have to do it over again after some tinkering.
