Comment 0 for bug 700878

Found while debugging bug #694283. Bzr blame is restricted to comparing the a revision ID with the current rather than operating on any arbitrary pair. Following a 'bzr diff' to confirm my hunch, I want to trivally alter the command to perform 'bzr blame' on the same time period:

  ubiquity$ bzr blame -r tag:2.2.23..tag:2.4.8 ./gui/gtk/stepUserInfo.ui
  bzr: ERROR: bzr annotate --revision takes exactly one revision identifier

The easiest thing to do would be to take the highest entry in the range and perform 'bzr blame' with that.
