So maybe the squeeze-slashes entry should mention something to the
effect that disabling it will only allow other options to do stuff,
but maybe nothing will. But in a less stupid way.

Right, just wanted to be complete. :)

I retried this with bindkey '^I' complete-word; setopt globcomplete.
With or without your patch, ls /*/*/cit completes to
/home/mikachu/citat and /home/mikachu/citat-private and lets me cycle
between them. Without your patch, ls ///cit completes to /tmp/citat
and /tmp/citat.private. With your patch, ls ///cit acts as /*/*/cit
did, which makes me happy. All of this of course with squeeze-slashes
off and path-completion on.

This seems to work great in my zsh -f. My next project is working out
why none of this helps with my zshrc loaded :). Thanks.
