Uh, I came up with a cleaner one, I think.  I didn't test
--enable-integer-datetimes yet.

I tested a few of your examples:

	test=> select '41 mon 10:00:00'::interval / 10 as "pos";
	          pos
	------------------------
	 4 mons 3 days 01:00:00
	(1 row)

It basically rounds the remainders to full values if they are close to
full (+/- 0.000001).
