Apologies, I was wrong, here.  When the terminator is \n, comment-end is
"", not "\n", and things get confused.  comment-end is NOT and NEVER WAS
the comment terminator.  It's merely what gets inserted when you type
M-;.  I don't think there is a variable which holds the comment
terminator; there is merely an entry in the mode's syntax table.

The rest of my post was largely speculation, and was also wrong.  Please
ignore it.
