You can use the --all switch to countermand that, AFAIK.

Doesn't this mean that your comments about fontconfig customizations
are not relevant to the issue at hand?  AFAIU, Glenn mentioned
fc-match as a way to explain what he meant, he didn't really mean
Emacs to run that command.  If Emacs cannot use its output, then its
configuration by users will never affect us.

And we are back to the original issue: suppose Emacs does run the
_equivalent_ of the above (I mentioned one way of doing it in Emacs):
is there any doubt that someone somewhere will find the results not to
her liking and would like to see the Info-quote face identical to the
rest of the text in an Info buffer?  If so, then trying to use a
fixed-pitch font, even if it's other than Courier, will never succeed
to be a "one size fits all" solution.
