} Ouch ;-) There was already the cvs tag.
} For now this patch makes command names be preceded and followed by two
} colons. I.e. to unambiguously match the command name you can now do
} `*::cvs:*' and to test for a command/tag combination: `*::command:*:tag'.

This only solves the problem in one direction, doesn't it?  That is, now
you can tell that tag is not a command name, but how do you tell that a
command name is not a tag?

What I mean is, if testing "*:cvs:*" to find the cvs tag, but the context
is "...::cvs::..." because the command name is "cvs", then the tag branch
is going to be taken because "*:cvs:*" matches both "::cvs::" and ":cvs:".
It's a pain to have to test "*[^:]:cvs:*" just to be sure, especially
since that won't match if "cvs" is the first thing in the context (or is
that impossible for a tag name?).
} And I forgot to say that before the next release we should make sure
} that we set up good defaults for styles and probably improve the
} default _sort_tags. But I think this should really be done at the end.

I still need some good examples of styles.  As I mentioned before, I'd
never done much with compconf, so I didn't have anything for the "new"
compconf to convert into styles.  Consequently, I'm now back almost to
the bottom of the learning curve in understanding exactly what I can or
might want to do, and how.
