No idea what then. With /// (//// takes a bit too long), I get all
sorts of stuff completed, dev/disk/by-label/, proc/sys/debug/ etc.

It acts the same way for me, but ls /tmp/ff/<tab> with no files there also says
---- no match for: `arg', `directories', `file', or `corrections'
so I don't think it's because of squeezing or path-completion. Same
with accept-exact-dirs off. It seems logical that if the final result
isn't accepted when typed explicitly, it isn't produced from a partial

There's the preserve-prefix style. With it set to //, ls ///<tab> acts
the same as ls //<tab> without it set. So that's something at least.

Yeah, emulating 'locate' extremely badly isn't my primary use-case :).
You can say the same thing for /**/<tab> too. (Though this seems to
behave as a single * in my zshrc, but does hang for a long time from
zsh -f + compinit, another mystery).
