bug#50506: 28.0.50; display-line-numbers equivalent for linum-format?

[Michael Gallagher - NOAA Affiliate]

Thank you all for the replies.

Lars, I do this already but it only really helps most when it's high contrast (white --> black) like you've shown here. And with that, it hurts my brain for other reasons... I swear I'm not overly sensitive.

Eli, as far as your suggestions, these requirements make sense to me. I took a crack at modifying xdisp.c and was able to display ascii characters by appending to lnum_buf before the numbers are displayed. However, when I tried to hook that into the lisp code and add a variable so that it wouldn't be hardcoded (a must, of course) I fell flat on my face. Converting between character lisp variables to the appropriate C types is above my "undergrad CSCI refresher" pay grade. I wish I could be more helpful but if I were to be the one to submit a pull request I would probably need someone to hold my hand.

Best,

Michael

Does it help to customize the `line-number' face to something that has a
different background colour than the main text?  For instance, setting
the background colour to black gives me this:
