Interesting. According to Completion/Debian/Type/_debbugs_bugnumber it
uses the cache directories from the "bts" command to look for bug
numbers, so it will only complete bug numbers for bug reports you've
already viewed with the "bts show" command.

Nice!

It won't help in my case as the only bts subcommand I use and which
downloads bug reports is "bts --mbox show".

So to support the mbox based caches, similar code, but parsing out the
first subject line out of each mbox should suffice.

Then again, don't do that effort for me, it's just a general thought based
on my usage of "bts":

* I use "bts --mbox show" (aliased to "btsmutt" :-) usually on my mail
  server, because that's from where I send mail. And I usually use
  that command because I want to reply to a bug report I'm not
  subscribed to (yet).

* I use "bts tag" and friends (all the commands which modify bug
  reports) usually on my workstation. There's usually no bts cache at
  all on my workstation.

Sounds sane.
