bug#33967: [Feature Request] Use proportional fonts in Info-mode

[Alan Mackenzie]

Hello, Alex.

I'm happy to do without such "improvements", taking advantage of the high
readability of my terminal's fixed width font.  I take it you really mean
"have the option of using proportional fonts".  I've nothing against
that.

I'm not sure whether proportional fonts really do improve readability.
My standard test is to use such a font to display the notional C
fragment: "Legal||Illegal" and check that what's displayed isn't just an
indistinguishable mass of vertical lines between legible characters.

However, you're probably aware that TexInfo formats text into lines, with
line breaks.  These may not display well with proportional fonts.

I'm wholly unconvinced that making Info "better match" HTML is at all
worthwhile.  Where's the advantage in such a match, even supposing it is
possible?
