Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)',
and a couple of functions that were missed in the previous batches. Not
terribly tested, but very carefully scrutinized, three times.

All these were found by the little findkrc.py that I posted to python-dev,
which means there might be more lurking. Cases such as this:

long
func(a, b)
	long a;
	long b; /* flagword */
{

and other cases where the last ; in the argument list isn't followed by a
newline and an opening curly bracket. Regexps to catch all are welcome, of
course ;)
