While it is true that loss of "else" will not change what the code
means, this change feels subjective and I'd say it falls into "once
committed, it is not worth the patch noise to go in and change"
category, not a "clean-up we should do".

I haven't looked at diff-merges.c for quite a while, but I did.  I
notice that the code is barely commented on what each helper
function is supposed to do, etc., and very hard to follow.  The file
needs cleaning up in that area a lot more, I would say.

Thanks.
