Re: Change `customize-save-variable' to work under "emacs -Q"?

[chad]

Since we sometimes want custom to set variables in spite of -Q (for reproducing 
bugs, which I'll guess is probably the most common use of -Q) and sometimes 
don't want that, can we make it a switch?  

I was hoping to suggest a patch, but setting debug-on-entry for 
customize-save-variables and running Emacs -Q under MacOSX caused a crash, and 
I don't have the attention right now to hunt it down *and* suggest a patch.  
Customize itself seems to check 'init-file and offers different text if it's 
not set; is that sufficient for either asking something like ``Can't save 
setting; set for session anyway?''?

*Chad

P.S. In case someone cares about the crash, I've attached the system's dump; it 
might just be an artifact of the way I ran Emacs -Q.  If I can reproduce it, 
I'll file a bug/patch.
