Indeed, that's a bug.  A related bug that can be seen in all programming
modes is that if you type something like

     // some comment (and some
     // side note).

the final ) will not be matched to the opening (.  It will either raise
a "mismatched parenthesis" warning or will be matched to some
unrelated open parenthesis.

Your case is slightly different since the paren is actually part
of the comment-marker rather than being inside the comment, but the
problem has basically the same origin.

I don't expect we'll fix this problem any time soon, tho.
