  It might be rather unfortunate to remove the configure line from
normal invocation. It speeds up trouble shooting and can be helpful
when working on bug reports.

  Printing it in a nicer way and splitting over multiple lines sounds
like a good idea though. But try to do it in the simplest and robust
way you can think of. Over-engineering won't add much value here and
some trouble in the worst case.
