`comment-end' is "" by default.  Setting it globally to something else
will lead to errors in various major modes which assume that "not
setting comment-end" is the same as setting it to "".

I.e. the global setting of comment-end should not be change(able|d).

This said, your report probably points at another bug because the
"*/\n> " should not be added to lines which don't start with "> ".
