Bug Description

"bzr diff --using meld" used to be a really useful way of comparing revisions. One of my favourited used to be "bzr diff -r :submit --using meld" to see the local changes compared to upstream.

This gave me a single meld window with all changes, including new and removed files.

Now most of the output goes to stdout as ordinary diff, and meld is instead invoked once per changed file (the output on stdout seems to be regarding the new and removed files)

I'm pretty sure the difference is that Scott was using bzr-difftools
which has explicit meld support and provided a different 'bzr diff
- --using' implementation than just the builtin 'bzr diff --using' support.

I don't have any package installed called this, and indeed can't find
one named that in the archive.

Scott: I don't think that this plugin was ever "debianized". Hence it
is likely that you manually put a copy of this plugin in
~/.bazaar/plugins. The behavior you described accurately describes the
behavior of this plugin. (https://launchpad.net/bzr-difftools)

The plugin achieves this behavior by writing the whole trees to a temp
dirs on disk. When one of the trees is the working tree, it just
passes the working tree, rather than a temp dir. This results in non
versioned, and ignored files showing up in the diff.

I intend on addressing this issue by fixing bug 490212. This will
address the usability issue of only been able to see 1 file diff at a
time. I did not realize that there is an issue with add/removed files.
I will give some thought to this.

If I did that, it would still be there - it isn't.

Gary, can you give an update on this? I'm assuming you have stopped specifically working on it, since the last update in the associated branch is 1 year old.

Would you be able to describe where you got to?
