[PATCH] tests: fix test regression due to additional output

[Eric Blake]

This test has been failing since commit 5285ea8c (sadly, since
last July; thankfully, unreleased).

* tests/m4sugar.at (m4@&address@hidden: nested): Fix test.

Signed-off-by: Eric Blake <address@hidden>

Pushing this now.  I guess the long lapse in fixing this is
a sad sign that I don't have as much time for autoconf as
I would personally like.
