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

[Michael Gallagher - NOAA Affiliate]

OK. Here we go. I found some time last night. Attached is a git patch file for changes that implement this feature request as well as (GNU) diffs for the individual files in question. It's a pretty simple commit. It's worth noting that I'm probably overlooking something in how I create the glyph, I definitely don't understand the nuances of the display code. But I hope it's helpful.

I think if you look up all the pieces that handle
display-fill-column-indicator-character, both in C and in Lisp, you
will have your answers.  Feel free to ask specific questions if
something is still unclear after that.
