[ Time to use zstyle instead of compstyle (but maybe you just used it
for output?). ]

I've already explained this at least twice. The problem is that the
completion code gets a PREFIX of the form f/*/b with
`compadd -p foo/baz/ - bar'. It tries to match `foo/baz/' with `f/*'
which doesn't work, because we can only either match the whole thing
with pattern matching (messing up braces and things) or do what we do
now, i.e. try to match the prefix (and suffix) normally and use
pattern matching for the strings (like `bar' in the example).
But we can try to make _path_files a bit cleverer... the patch below
makes it stop its ambiguous-part searching loop if it arrives at a
part with a pattern. It then changes the way the cursor style is
tested to hopefully give more sensible behaviour.
Andrej, is this, finally, acceptable for you?
Bye
Sven
