Variadic macros cause problems with cpphs

[mithrandi]

It seems that the variadic macros used in some of the shims cause... issues... with cpphs. Demonstration of the problem:

mithrandi@verdant /tmp> cpphs --cpp -P -C foo -o bar
mithrandi@verdant /tmp> cat foo
#define FOO(args...) f(args)
FOO(1)
FOO(1, 2)
FOO(1, 2, 3)
mithrandi@verdant /tmp> cat bar

FOO(1)
f(1)
FOO(1, 2, 3)

The good news is that there seem to be very few invocations of these macros that actually pass multiple arguments, so I think it should be fairly easy to make these macros non-variadic, which would avoid the problem. Would this be a reasonable solution?

yes, i'll do this in improved-base
