Argument declaration style (Was: ANSI C prototypes)

It consumes more width than your style, but it also consumes less height.  I
consider that a useful tradeoff, as it makes it more likely that the entire
function will fit on a single screen.  (Also, I very rarely have a function
whose prototype doesn't fit on a single line.)

This is interesting, because I use the exact same argument in *favor* of the
new style.  If you write
	void foo(x, y)
	  char *x;
	  int y;
	{
and you grep for the declaration, you don't see the types of the arguments.
(And it's even worse if you put the "void" on a separate line!)  With
	void foo(char *x, int y) {
you see all the relevant information at once.  Even with pre-ANSI code I use
	void foo(x, y) char *x; int y; {
for the same reason, but the invention of prototypes made most lines shorter.
