+Print the configuration settings
Print the arguments that were passed to @command{configure}.
I've had a similar line in an early version of the patch. However, it's
not *quite* correct, technically. We drop a few options when setting up
$ac_configure_args (--no-create, --no-recursion, --silent, some duplicate
arguments), and we add precious variables that came in from the
environment. A configure script invoked by a higher-level one through
recursion may be passed --srcdir and mangled --cache-file arguments.
Also, we don't guard against the configure.ac author mangling
$ac_configure_args.
So, the above formulation seemed more cautious to me. But hey, if you
think being explicit here is better, that's ok with me, too.
