Actually, I went to factor out the duplicate printf uses, then
noticed some underquoting problems (i.e., when $abs_srcdir expands
to something pathological, including e.g., semicolons or other shell
meta-characters), so started to fix those, and then went ahead and
converted to using test-lib.sh, so that this test now creates temporaries
in its own private directory (better for running tests in parallel).
As such, it doesn't have to use temp file names including ".$$" and
no longer has to remove them explicitly.  Also, there's no need to
rely on /bin/bash in this particular case.

Here's the new version.
It also required the following small changes to TEST_ENVIRONMENT
in Makefile.am.
(however, if an older automake we care about doesn't have abs_srcdir,
the RHS will have to be `cd '$(srcdir)'; pwd` instead)

Dan, you're welcome to fold these changes into your patch.
Or just commit what you have and I'll do this separately.

    expected="$data_dir"/`echo "$f" | sed s+\.conf$+\.out+`
    if compare "$expected" "$f-actual"; then
        msg=OK
    else
        msg=FAILED
        fail=1

    printf "%2d) %-60s      ... %s\n" $i "$f" $msg
