Don't only Ctrl+u/Ctrl+u scroll half a page?
It seems this patch is deleting the u/d keys again, which as far as I
understood should remain as a full-page scroll?
(If I misunderstood something, please forgive me; I never knew about
these shortcuts in less(1) before this discussion.)

Style-wise, I would prefer /= 2 over >>= 1. This makes the code more
accessible to people who are still in the process of learning C. Modern
compilers are smart enough to implement division by 2 via bit shift.
