Hello Eric,
Wow.
There is only one tiny nit I can find to pick (and I tried hard ;-)

The last sentence makes me stumble a bit. Did you mean "But with
@code{m4_expand}"? In case you didn't, then the "But" makes little
sense, as the previous sentence dealt with m4_quote, too. In case
you did, which I believe, a minor style nit that "but" is best not put
at the beginning of a sentence ("... whitespace, but ...") or replaced
by "However,".
Cheers,
Ralf
