Re: kill signals

Would it be reasonable to suggest that an optional parameter be added to
the kill command specifying which signal to use? This would follow
naturally from the unix kill command, and would provide a satisfactory
mechanism to deal with the problem described below. Inasmuch as quit
works by killing all windows, it could also take a signal as an optional
parameter.
