Thanks a lot.  I use v4.0.2 on Linux/x86 and had to
change the  "VAR+=STHG" line to "VAR=${VAR}STHG", and
similarly for the array, after I patched and it worked
like magic.  The same thing also worked for v4.0.6 on
SunOS/sparc and v4.0.6 on Cygwin_NT-5.0,Win2k/x86. 
Nothing broken so far.

Sorry about the ersatz OS/CPU terminology.

Regards,
harik

This is fixed in the latest 4.1 version (the main trunk) in the archive.

The patch was the one below.  I don't know if it works in 4.0, but
there's a reasonable chance.  It's had only limited testing, so any
feedback is useful.

ClearCase version-extended filename completion

[Hari Rao]

Hello zsh-users,

Version-extended file names in ClearCase (e.g.,
"foo.c@@/main/1") complete correctly (Type "foo.c@@/"
and press tab) only while using old-style completion. 
No completions are displayed once you activate new
style completions by calling "compinit."  I understand
from earlier threads* that this can be fixed by some
changes to the "_files" function, but haven't been
able to figure out the changes required.  Has anyone
already done this or can explain to me what needs to
be done?

Thanks a lot,
harik
