Personally, my perferred style avoids confusion.
If a keyword is followed by a '(', I seperate them by a space.
Admittedly,
	while(expr);
looks like a function call, but
	while (expr)
		;
does not.
Clear style is up to the programmer.
Function calls should "look" like function calls,
macros should look like function calls, but
"return"s should not look like function calls.
