That is correct, yes.  The patch was working and ready, but I took
Stefan's criticisms on board, and I think he was right.  It was a fairly
large change to syntax.c with a minor gain.  Also, it would have meant
having two alternative comment mechanisms in CC Mode for a few releases.
So I think on balance, it would be better to regard the patch as an
experiment only, which should go no further.

I think the bug should stay open, though.  CC Mode still doesn't handle
multi-line comments absolutely correctly, and these could surely be
fixed, like Stefan said, by using syntax-table text properties somehow.

I also created a plethora of syntax test cases for the patch, some of
which are applicable to syntax.c as is.  I'll get around to sorting
these out and committing them sometime.
