Sorry about that.  I have fixed it, and now use a more sophisticated  
approach to strip off the units that will find them even when there  
is no leading space.  But since the %Units::known_units hash is  
private, the pattern is a little more aggressive than it ideally  
would be.  This shouldn't be a problem for well-formatted answers,  
but some erroneous answers may get unhelpful messages.  For example  
entering "3x" would give an error about unknown unit 'x'.  The regexp  
approach is never going to be perfect, but the better approach would  
be to make a proper units class for the Parser.
