Hi Martin,
I haven't yet dared to review 1/2, which is the interesting change. So I
cheated and skipped to 2/2.

Perhaps you could split those changes off in a separate, trivial patch.

And perhaps even send these two changes as two separate patches. Not
sure, as I don't review much, but it should make it easier to review.

Could you make this match the code? Ie,
/* (a='b') && (a!='c') -> 'b'!='c' ? a='b' : 'n' */
if I'm reading the code right.

Likewise:
/* (a!='b') && (a='c') -> 'b'!='c' ? a='c' : 'n' */

(You could also make the code match the comments. But that would make
the patch less trivial.)
