longobject.c's x_mul()'s special code for squaring gets kind of sloppy at the end of a digit pass, doing a useless add of 0 and an "extra" test for carry. Easily cleaned up.

I think the underlying cause is that the HAC algorithm description it was modeled on was quite "hand wavy" about how badly, and exactly when, the carry can exceed a single digit. Things are better-behaved at the end of a digit pass.
