The emacs-24.2 tag was definetly NOT there and as there were comits in
the log with timestamps indicating they had occured on the day I was
checking, I assume things were up-to-date.

What I am gussing has occured is that the emacs-24.2 tag was not added
to the emacs-24 branch *before* the merge into trunk and was added to
the 24 branch after the merge. This would mean it would be in the
emacs-24 branch but not in trunk. If the tag had been created prior to
the merge, then I would expect it would show up in trunk?

Don't believe I'm doing anything unusual - pretty standard stuff really.

I find dealing with bzr more effort and somewhat more confusing than
any other system I use. I can't explain why and I'm not pushing for a
change in what is used for emacs - for whatever reason, I don't find
bzr at all intuitive or natural. It is also used by only two projects
I deal witih and consequently, does not get enough use for me to
remember much more than the basics. I have to constantly go back to
the manual to work out how to do something I did only a few weeks
back. Unless/until I find more things I'm interested in using based
around bzr, this is unlikely to change.

Not a great alterantive unfortunately. I've actually tried that
approach a while back. The problem is in deciding when something is
stable/good enough to tage as such. Too often I found I'd tagged
something as supposedly stable and just a little while later, run into
something that cripples usability. I do find tags useful sometimes for
other forms of tracking, but not for identifying good stable versions
(at least no more useful than using the commit log).

After seeing Glenn's message, I updated and the emacs-24.2 tag is now there.
thanks Glenn. I apologise for this causing as much noise and
speculation as it did - it wasn't what I expected.
