Sanitizing a branch (I got a result)

For this specific, almost certainly once-only per project use
case,  it was simply to remove files that should never have
been added in the first place. Examples of this:

  - Text files containing a mailing list thread describing how
    some new feature should work. After the new feature as added
    there is no need for these files to remain.

  - Sound files, sometimes quite large, which trigger a particular
    bug. They were added to Bzr so that I  could work on the
    problem on more than one machine (in particular different
    CPUs) and once the bug was fixed, deleted. However, the file
    remained in the history so I didn't want to make the branch
    public.

I can see other things being useful, but that was my particular
requirement.

Cheers,
Erik
