What is 'bzr diff -r 1..2 http://path/to/branch supposed to do?
- Diff revision 1 of http://path/to/branch against revision 2 thereof
- Diff revision 1 of . against revision 2 of http://path/to/branch
- Diff revision 1 of http://path/to/branch against revision 2 of .
Guess reading --help would tell me, but it takes a hack lot thinking each
time I need to use it. The ;revision notation would really help here:
  bzr diff .;revno=1 http://path/to/branch;revno=2
can't be confused.
Note that it is longer, so it should not replace -r completely. Though one
could write:
  bzr diff http://path/to/branch;revno=1 http://path/to/branch;revno=2
with a bit of shell magic as:
  bzr diff http://path/to/branch;revno={1,2}
