Currently, when compression is enabled, hdisplay is reduced via integer
division. This causes issues for modes where the original hdisplay is
not a multiple of 3.
To fix this, use DIV_ROUND_UP to divide hdisplay.

Nit: probably these should go in the opposite order. And if they're
all supposed to be chronological, I think it is:

But unsure if that's a hard requirement, or even correct at all.
Hi Marijn,
I don't see any explicit documentation on the order of R-b tags. FWIW, I
see in the git log that S-o-b always goes at the bottom of the commit
message.
I would prefer the S-o-b to always be at the bottom (as it helps me
avoid duplicate S-o-b's when doing `git commit -s`), though I can flip
the order of the R-b and suggested-by tags.
Thanks,
Jessica Zhang
