[Matthew D Truch]

SVN commit 481042 by truch:

Allow positive numbers to start with a '+'.

Sometimes, for reasons no known to me, people make damn sure you don't
think they have a negative number by putting a + in front to mark it
as positive.  These people have been known to work in the Spectrum 
Analyizer division at Stanford Research Systems.
