Re: parseopt with negative numbers as positional arguments

[cblake]

It might not be quite as CL-user transparent as what you're looking for, but 
having the CL user quote a space in front of the number usually works as in: 
    
    
    tempconvert \ -10 F --to=C
    
    
    Run

or 
    
    
    tempconvert " -10" F --to=C
    
    
    Run

You might need to strip the whitespace off pre-parsing depending on what 
integer parser you are using.
