[Bug 788747] [NEW] requesting diff of one file gives output of all changes

[Scott Moser]

Public bug reported:

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
