I tried it, and I had to underquote not only the _m4_defn in m4_require
(which might be okay, since defn overquotes), but also the call to
m4_divert_require:

-      [m4_divert_require([_m4_divert_desired], [$1], [$2])])])
+      [m4_divert_require(_m4_divert_desired, [$1], [$2])])])

So I'm inclined to leave it as in the already-posted patch.
