That makes no sense.

Do you write your normal variable definitions like

int
a,b,c;

too? No you don't, because that would be totally idiotic.

A function declaration is no different. The type of the function is very
important to the function itself (along with the arguments), and I
personally want to see _all_ of it when I grep for functions.

You should just do

grep -i '^[a-z_ ]*(' *.c

and you'll get a nice function declaration with the standard kernel
coding style.

And I personally don't normally do "grep for random function
declarations", that just sounds like a contrieved example. I grep for
specific function names to find usage, and then it's _doubly_ important
to see that the return (and argument) types match and make sense.

So I definitely prefer all the arguments on the same line too, even if
that makes the line be closer to 100 chars than 80. The zlib K&R->ANSI
conversion was a special case, and I'd be happy if somebody were to have
the energy to convert it all the way (which implies moving comments
around etc).
