Completion problem when `nocaseglob' is set

Completion problem when `nocaseglob' is set

[John Cooper]

I've just upgraded to zsh 4.3.4 (via Cygwin) and have found that
completion in the root C: drive no longer works when I `setopt
nocaseglob'. It was working fine with my previous version of zsh
4.<something> that I installed a couple of years ago, but I don't recall
the exact version.

After running `zsh -f', the following both work fine and list the files
in the root of my C drive:
$ ls c:/<TAB>    # lists files as expected
$ ls /c/<TAB>    # lists files as expected

  (btw, I have the cygwin drive prefix set to "/" instead of
"/cygdrive")

The problem starts when I set the `nocaseglob' option:
$ setopt nocaseglob
$ ls c:/<TAB>    # no files listed
$ ls /c/<TAB>    # no files listed

A couple of years ago I experienced the same problem and, after getting
help from this list, I resolved it by doing:
$ mount -c /cygdrive
$ /usr/bin/mkdir /c
$ /usr/bin/mount -c /

Apparently, creating the /c directory allowed it to become visible to
the globbing system (it's listed in `print /*'), although I don't
understand why this is only needed when `nocaseglob' is in effect.

Anyway, with zsh 4.3.4, the above is now only a partial fix:

$ ls /c/<TAB>    # lists files as expected
$ ls c:/<TAB>    # no files listed

Does anyone know how I can get completion to work using c:/<TAB> with
zsh 4.3.4 with `nocaseglob' enabled?

I've tried the following, but to no avail:
  zstyle ':completion:*:paths' accept-exact 'c:'
  zstyle ':completion:*' fake-files '/:c'

Thanks,

    --- John.

This is a bug that was fixed in 4.3.5,

2007-10-23  Peter Stephenson  <pws@csr.com>

	* users/12087: Src/glob.c: fix a case where we doing globbing
	unncessarily to find files case-insensitively in Cygwin.

Thanks for letting me know. 4.3.5 isn't available yet via Cygwin's setup.exe, so I've installed version 4.3.2, which doesn't exhibit the problem.

I'd like an new version with c:/ completion as well!
