Mystery bug acks

[Ian Jackson <ijackson@chiark.chu.cam.ac.uk>]

I've just received `bug closed' messages from the bug tracking system
for 5 of my bug reports, but no message from anyone saying why they'd
been closed.

As the bug tracking system's ACK says:
 You should be hearing from them with a substantive response shortly, if
 you have not already done so.  If not, please contact them directly,
 or email debian-bugs@pixar.com or myself.

Instead of mailing debian-bugs (generating a new report) I have
reopened the five reports in question.  I'd be grateful if the
maintainers would advise me why these reports were closed - the
conventional way to do this is to CC the `done' message to the person
who reported the bug (me, in this case).

Thanks,
Ian.
