:echo $visual shows now:

   =mutt   or   =inbox

I only need to get rid of the trailing =, but I can't find the way to do 
it with grep.  I think that this should do it:

   folder-hook . 'set box = `echo $visual | sed \'s/=//g\'`'

But it doesn't.  I get a too many parameters error.  I guess it has to 
do with the nested quotation marks, but I don't see how to do it.

Cheers,
