Code review comment for lp://staging/~cjohnston/launchpad/187013

Hi Chris,
thanks for these fixes.
In bugsubscription.py I found this:
"Your subscription to this bug has been updated."
That should probably read "bug report subscription" for consistency? Are there other cases that should be adapted?
Sorry if I seem nit-picky here but I want to avoid more of these little bugs being filed in the future if we can do it right right now.

Thanks again!
Henning
