Thank you for the pointer.

As I said, I have a patch.  The patch includes an addition to the line4.c test
case.

What is delaying this is my testing of the change.  Specifically, I am
configuring, building bootstrap and building check for both the patched and
un-patched code then comparing the results.  The comparison was throwing up
many spurious differences due entirely to the slightly different directory
names I was using in the configuration process.  I think I now have those
details worked out, but there are still spurious differences due to temporary
file names, but I think that I can get past that.  It just takes hours for the
builds to complete...

Argh! -- someone put in a patch that I didn't track properly.  More details to
account for and another round of delays.  It'll be done when it's properly
tested.
