Actually, the autoconf manual strongly recommends _against_ using
changequote, for the reason that people tend to forget to unset it,
and for the reason that any subsidiary macro expansions during the
time when changequote is active will fail to behave as expected
because the helper macros assume (and rightly so) that changequote
is not in effect.  I would prefer sticking with proper quoting than
relying on changequote.  Not to mention that a future version of
autoconf may be fixed such that you would be required to use
m4_changequote instead of changequote to match the documentatioin
of m4sugar, whereas proper quoting will never be broken.
