such files really exist.
such files really exist. The dir may be a pattern; pattern characters
or colons in var(dir) should be quote with a backslash to be treated
literally.
This can be useful on systems that support special filesystems whose
top-level pathnames can not be listed or generated with glob patterns.
It can also be used for directories for which one does not have read
permission.
The pattern form can be used to add a certain `magic' entry
to all directories on a particular filing system.

hit for anyone not using PINE. The previous default can be restored with:
zstyle ':completion:*' pine-directory ~/mail
The completion style fake-files now allows patterns as directories,
for example the value '/home/*:.snapshot' is now valid. This will
only cause problems in the unlikely event that a directory in the style
has a pattern character in it.
The default maximum function depth (configurable with
--enable-max-function-depth) has been decreased to 1000 from 4096. The
previous value was observed to be large enough that crashes still occurred
