bug#33772: StumpWM broken commands?

[Christopher Lemmer Webber]

It seems to me that StumpWM broke somehow, for some reason.  I can
confirm there was a version change:

address@hidden:out        
/gnu/store/i0picr2xr2aq2a52nsaw67nvar1r3khw-sbcl-stumpwm-18.05
address@hidden:out        
/gnu/store/6h2iln76dx8pxdp1hsaqb1yncm8viczj-sbcl-stumpwm-18.11

I am not sure if this is the cause or something else.  At any rate, when
I try to run commands such as "gnew" (the command to make a new
group/workstation) I get back:

  Error In Command 'gnew': invalid number of arguments: 2

I though I'd try running the command manually and check the error, but
this also happens with eval!  Some other commands are not affected.

(I can try re-enabling the live REPL in StumpWM to play around with it,
but I currently have it off because they have the same live hacking
vulnerability in SBCL/SLIME that we had in Guile/Geiser some time ago.)
