Title:
  requesting diff of one file gives output of all changes

Status in Bazaar Version Control System:
  Confirmed
Status in “bzr” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: bzr

  The current lp:ubuntu/python-boto branch is a bit screwed up (to be
  fixed in bug 788736), but it illustrates a bug in bzr.

  $ bzr diff -r tag:1.9b-1..tag:1.9b-1ubuntu1 debian/rules  | diffstat -p1

  Above I requested a diff of a single file (debian/rules) but the
  entire diff from the two revisions was given.

  I've attached the .bzr directory of lp:ubuntu/python-boto for reproducibility.  Grab the attachment, then:
  tar -xvzf python-boto.tar.gz
  cd python-boto
  bzr revert # to restore the files I deleted to save space
  bzr diff -r tag:1.9b-1..tag:1.9b-1ubuntu1 debian/rules  | diffstat -p1
