GNU style is a space between "void" and "*", so this should be '.I "void\ *"', both here and elsewhere. The backslash prevents a line break.

Change "cast" to "convert", since the point is that no cast is needed.

%p works with any object pointer type (or in POSIX, any pointer type), not just void *.
Should also mention "void const *", "void volatile *", etc. Plus it really should talk about plain "void", saying that it's a placeholder as a return value for functions, for casting away values, and as a keyword in C11 for functions with no parameters (though this is being changed in the next C version!). I sent comments about most of this stuff already.
