Won't a line number like L1234 look worse with this
"monospace-ization" than it looks when displayed "normally"?  AFAIK,
proportional fonts are designed to look well when each glyph is
displayed with its advance width in the font.  Overriding the advance
width in many cases looks like some extra spaces added between
characters, which is annoying, looks like a bug in display, and gets
in the way of reading, IME.

I only meant that as a means to try and see what will such display
look like, without changing anything in the display code.  Just to see
what we will get before we implement it, and decide whether it's worth
the trouble.
