`char' parameters

I was bitten by the float/double version of this once.  I had declared
a formal parameter as a float, took its address and passed what I
thought was a float pointer to another function.  Anyway, I don't have
K&R 2nd edition around, but K&R 1st edition does describe float formal
arguments.  From page 205:

	C converts all float actual parameters to double, so formal
	parameters declared float have their declaration adjusted
	to read double.

Your're right though, that int vs. char is not explicitly mentioned
in this section.
