That is really a good one to dig out. So in short, X was needed
because we wanted to use F, and we could drop it if everybody is
using recent versions of less, but the default to use FX at the same
time gives us the same behaviour between both newer and older
versions of less.
Please note that dropping "-X" and leaving "-F" would actually introduce
the inconsistency that I already mentioned. To reiterate, short outputs
would then remain displayed on screen, while long outputs would
disappear after exiting less(1). I don't think that's the desired
behavior.
... And as you say, if there are people who really
care about their LESS options, it is easy for them to override it.
Yup. I really like the discovery of that changelog entry.
Thanks.
