Nope; Bruno already listed this as failed attempt #2 later in his mail.

Besides, there are very few places where using m4_quote will ever help
you, where adding extra [] in the correct location wouldn't have already
solved it in the first place.  That, and m4_quote can lose leading
whitespace (if you are willing to require newer autoconf,
m4_expand([$1]) is almost always better than m4_quote($1)).  m4_dquote,
on the other hand, is used rather frequently.
