Hmm, we might want to define -redirect-,<,-default- and would want
patterns tried before that. I think the post-patterns should perhaps be
tried just before -default- is first tried in the command position for
redirection and in the parameter name position for values. Or perhaps,
we need to look to see where each post-pattern uses -default-. If it
uses a pattern for one part then we should use it before trying
-default- for that part. We might need to require patterns to all be
of the form -whatever-,pattern,pattern.

I had. I'm not sure what was wrong but it all works now with the latest
patch. I may have had an old version of a function in my ~/.zfunc.

Ah, that is better, and neater than braces. I hadn't picked up on that
part of the idea. Very neat.

The patch below does the GZIP thing I mentioned. I've also added
pattern completions for *PATH and *path parameters using _dir_list and
_directories respectively. I've not thought of any exceptions where
this isn't appropriate but I'll leave sufficient time for objections
before committing.
