bug#32337: 26.1; display-line-numbers-mode makes cursor ill-aligned when number face is changed

[Carlos Pita]

Just to mention another related issue a reddit user pointed out: in an
empty buffer the cursor starts at a weird position because of the
"invisible" line number indicator in the EOB line. Possible
improvements on this: use the line number face with a non default bg
color and/or add a special char to the EOB line indicator.
