Re: Limit looping in Grob::common_refpoint (issue 4079) (issue 134600043 by address@hidden)

Set saner limits, fixed indentation and copyright notice.

I have disregarded Mike Solomon's suggestion to issue a programming
error message because David is right about the right places for graceful
error handling.  The value of the Strict_counter comes from being simple
enough that one can understand it at a glance and trust it to catch
problems that should have been handled more gracefully but were
overlooked.
