In "u64toa()":

	If the byte being investigated is 0, don't just do a "continue";
	this might be one of the passes on which we have to propagate
	carries, so skip the processing of that byte's bits, but fall
	through to the carry processing.

	In the carry processing loop, don't use "i" as the loop index,
	as we're already using it as the outer loop index.

In "u64toh()", use lower-case letters rather than upper-case letters, as
we use "%x" rather than "%X" to print 8, 16, 24, and 32-bit integral
values in the "proto.c" code.
