Don't forget that prefix `-' and `--' are valid C operators.  You can't 
tell the difference between the above and a valid C expressions.  I 
think that rules `-...' out.

I also think it should be part of the ``set'' family.  I think it is 
entirely reasonable for a user to type:
	``show logfile''
set/show can be used in ways that avoid the need for parameters.
