The point is that in a number of places in the code, when it is scanning
along the pattern, it has code like

while (*ptr != 0) .....

or

(if *ptr == 0) ...

and no doubt written in other ways too. I don't know how many "a number"
actuall is. All those places will have to be found, and changed to
something like

while (ptr < cd->end_pattern) ....

Maybe "tedious" is a better adjective than "hard". I confess that I had
forgotten that end_pattern is already set up for newline testing; I had
thought it would have to be created, so not *quite* as much work as I
imagined. Of course, there is also the documentation to write.

I _have_ noted this request and will probably get to it in due course,
whenever that is. :-)
