Merge lp:~nmb/bzr/559072-missing-tag into lp:bzr

[Neil Martinsen-Burrell]

Add tag information to the output of bzr missing.

This fixes bug 559072 by adding tag information to the output of the "bzr missing" command. The signature of bzrlib/missing.py:iter_log_revisions() was changed, but only by adding a keyword argument to the end, so I didn't think that it warranted mention as a compatibility change. This had to be done to get tag information from the appropriate branch.

[Jelmer Vernooij (jelmer)]

Thanks for working on this, looks good.

It might be nicer to pass in the reverse tags dictionary rather than the actual branch; that seems more consistent with the other parameters that are being passed in (revisions). What do you think?

[Neil Martinsen-Burrell (nmb)]

I think that is indeed better. Change made in the branch. I also fixed it to print and test tags for the remote branch as well.

review: Approve

[Jelmer Vernooij (jelmer)]

This has a conflict in the release notes; any chance you can fix that?

[Neil Martinsen-Burrell (nmb)]

Fixed on lp:~nmb/bzr/559072-missing-tag.
