My patch also made any unparenthesized cmake macro/function call
FOO
equivalent to the same call without any arguments
FOO()

This required some changes to the parser/scanner.  I'd be happy to
regenerate it off cvs trunk, if there's interest...  I did run through
all of the tests, but did not think through all possible corner cases.
May be a devil somewhere down there in the details...
 
For now though I'm just grateful that a portion of the patch was
accepted :)
