Is there a common name for the A..B range format (two dots) that would
complement the A...B (three dots) symmetric range format's name?

I was looking at the --left-right distinctions and noticed that the trail back to the symmetric range description was rather thin (it's buried within
gitrevisions:Specifying Ranges, and even then its called a symmetric
difference.

I would just call it a range, or possibly a set difference. But I don't
think we have any established naming beyond that.

Yup, I think "range" is the commonly used word in discussions here.
When inventing A...B as a new thing in addition to A..B, we called
the former "symmetric difference", and what is implied by that is
the latter is "asymmetric difference"; we do not say that unless we
are contrasting between the two, though.

I asked because the man page does indicae that it (A..B) is a special sort of revison range and "there is a shorthand for it", but then didn't have a way of naming it.

The symmetric difference is then brought in as a further similar notation. There are a number of Stackoverflow questions about the differences betwee 'two dots' and 'three dots' as well, so having a word/phrase for it could help.

I was thinking that maybe "single-sided difference (two dots)" maybe one choice that is relatively neutral (or even a "two-dot range"...).
