Yes, I sent it off too quickly.  I attach a revised version of the  
patch, that fixes the typo, improves the parser by allowing  
parentheses in version range expressions, and adds a check that the  
new syntax is accepted only by cabal >= 1.8.

into the standard Cabal repo, I would be very grateful if you could  
test the revised patch and let me know of any remaining errors.
