In the event one gets diagnostic messages from _grops_ when its done with its
input stream--at which point its PostScript resource manager "psrm.cpp" can
still have much to do--those diagnostics report a line number of the maximum
line number of the input "grout" plus 1.  This is misleading nonsense.

_grops_ should reset the line number to zero when its `do_file()` finishes its
last meal.  _libgroff_'s diagnostic functions interpret that to mean that no
line number applies to the reported message.

Other output drivers should be inspected for the same problem.  I think
_grotty_ already does the right thing.
