Thanks for confirming.  However, the patch does slow things
down a bit, and it becomes noticeable in for example C files
when they reach a hundred thousand lines.

Do for example four times 'cat src/*.c >>testing.c' and then
run 'src/nano testing.c'.  When then hitting Enter or ^K, it
takes nano nearly a second to respond.  (Responsiveness can,
however, easily be regained by switching syntax colouring off
with M-Y.)

But... who in his or her right mind is going to edit files of
more than a few thousand lines?  Files that require syntax
colouring, that is.
