[STUMP] Syntax query: run-or-raise all-groups

[Johnny]

Hi,

I have the following code in my .stumpwmrc:

,----
| (define-key *root-map* (kbd "M-m") "alsamixer")
| (defcommand alsamixer () ()
|   "Start or switch to alsamixer."
|   (run-or-raise "exec xterm -name alsamixer -e alsamixer -c 0" '(:instance 
"alsamixer") :all-groups nil))
`----

However, it seems I am not setting the optional variable all-groups
properly, as it always searches through all groups to raise
alsamixer. What is the proper syntax here?

Thanks for any help!
