This series is confusing as the 3 patches here do not do all the things
described here.

It also doesn't apply to the master branch (e.g. PATCH 3/3 modifies
display.c, which doesn't exist until your other series.)

Please take care when writing these cover letters to be sure they are
accurate, otherwise reviewers/maintainers can't help but be confused
about what is going on.
