"Permission denied" PATH-searching bug

[Hrvoje.Niksic@xxxxxxxxxxxxxx (Hrvoje Niksic)]

I do not remember if this problem was reported, but it was present in all
2.6 beta releases of zsh. If you have a directory you may not read in your
PATH, any command not found in search find will be followed by "Permission
denied" error, instead of "Command not found".

jagor% something-not-in-path
zsh: command not found: something-not-in-path
jagor% mkdir forbid
jagor% chmod 0 forbid
jagor% PATH=$PATH:forbid
jagor% something-not-in-path
zsh: permission denied: something-not-in-path
jagor%

Experience has shown that this is extremely confusing to users, equally
newbies and experienced ones (excluding the ones having experience with this
bug:>). People often have a forbidden directory in their path, which means
they get "Permission denied" every time they misspell a command.
