The fact that half a dozen people so far have come up with this command
line should tell you something.

Here's how it works:

	for each file, i, that matches "*.[ch]"
		diff the copy of that file in "old" with the copy in the
			current directory, putting the output in a file
			of the same name but with a suffix of ".diff"
			appended.

Which is what your example does... but less explicitly.
