This may be useful as an addition to a general version number 
comparison, but for Emacs version numbers, I think we should DTRT based 
on the shorter of the two arguments:

(version= "22" "22.0.50.37") => t

Actually, I don't see why you need the second argument at all - won't it 
always be emacs-version you want to compare with?
