zsh doesn't complete for tar, zip, possibly other files

[Lewis Thompson <purple@lewiz.net>]

Hi guys

The subject is pretty much my problem.  I'd be very grateful if
anybody is able to help me resolve this one.

cheers, Lewis

partlow ~ % ls *.zip
First Ascent - Disk 2.zip  First Ascent - DVD Extras.zip  foo.zip
partlow ~ % unzip [hammering TAB]

Interestingly for tar I get different results:

partlow ~ % ls *.tar
foo.tar
partlow ~ % tar [TAB]
A  -- append to an archive
c  -- create a new archive
f  -- specify archive file or device
t  -- list archive contents
u  -- update archive
v  -- verbose output
x  -- extract files from an archive
partlow ~ % tar xvf [hammering TAB]

So clearly completion is trying to do something.  Other useful info:

partlow ~ % zsh --version
zsh 4.3.10 (x86_64-unknown-linux-gnu)

I believe these are all of my completion settings in .zshrc:
