Actually, I had expanded the vimdiff plugin so that it could take a
range of arguments, would set the temp files to readonly, etc.
But that was on another machine which I don't have access to (I was
working offline on a laptop).
I'll publish once I have access again.

At that point, I think it would be reasonably easy to allow a
configurable diff program.
And then change the name of the command to "bzr gdiff" for gui-diff,
with BZR_GDIFF being the command line.
Or we just leave it as a plugin, and if someone who wants a different
gui diff program can just edit those lines.

I know I like having access to both gvimdiff and vimdiff in case I am in
an SSH session, versus being local.
