Indeed, if the problem is with determining whether
line-number-display-width should be called, then bound-and-true-p is
the way.  Sorry I didn't realize this was the issue.

So does this mean the issue in this bug report (which AFAIU was how to
set the window's display margins in a way that is sensitive to
display-line-numbers-mode) is resolved for you?  Or is there anything
else to be done about this?  (Bug#28855 is a separate issue, I will
respond to that there.)

Thanks.
