Does it work as documented? E.g., I can enable
display-line-numbers-mode, and they will take up 4 visual columns
(numbers plus separators), but (line-number-display-width) returns 2.
Should I always use (+ 2 (line-number-display-width)) instead? That
would be the actual amount of "screen estate used up for line-number
display".
Can I rely on the extra value always being 2?
