FYI, the nontrivial bit of this patch is the double initialization of
at_suite_log (and related move of $at_dir handling): first time it may
be relative, and we haven't done the `cd $at_dir' step yet, the second
time it will be absolute.  We cannot easily move the cd step up because
its failure shouldn't happen with something like
  ./testsuite -C nonexistent --help

This is covered in the test suite, luckily.  :-)
