If all chars aren't the same width, it's impossible to align plain text
into a matrix, with each char exactly below the previous one.

I just have `custom-theme-set-faces' with default :family "DejaVu Sans Mono".
So I would expect that to be used if possible.

I think I built it a week ago. I've just rebuilt 00119c6, and the bug is
gone. So I guess it's fine to close this bug.  Just to add, in the old
build the curved quotes in Info weren't fixed width as well.

Thanks for reminding me to rebuild, I'll try to remember this for the
next bug report.
