I already modified killall based on the message I recently replied to.  
(My back email is split between thunderbird and balsa at the moment so  
I'm not sure I'm dealing with the backlog in order. Dealing with the  
old balsa stuff right now...)

So, what this patch does:

   Adds -s
   Removes the <1 (at least one argument) requirement

I usually put a blank line between the GLOBALS() entries filled out by  
option parsing and the remaining ones.

Hmmm... If -s is specified it should override -SIG (I.E. parse command  
line parameters as if they're all command names); with this patch  
"killall -STOP -s KILL" would accept but silently ignore the -s. And  
with no arguments at all it should give a help message.

And it's specifically -l that allows no arguments, otherwise it should  
emit help text.

I reimplemented it, but think I covered the general idea.

Thanks,
