There's a hint there, but no it is not entirely clear. This should get
cleaned up a bit.

>From 'bzr help diff'

  -p ARG, --prefix=ARG  Set prefixes added to old and new filenames, as two
                        values separated by a colon. (eg "old/:new/").

Here's an example:

$ bzr diff
=== modified file 'bar'
--- bar	2012-07-30 14:43:52 +0000
+++ bar	2012-07-30 14:44:09 +0000

Title:
  what does "a/:b/" stand for?

Status in Ubuntu Packaging Guide:
  Triaged

Bug description:
  On page:
  http://developer.ubuntu.com/packaging/html/udd-patchsys.html

  I have difficulties to understand, what in $ bzr diff -p "a/:b/" > ../bug-12345.patch
  the part "a/:b/"  stands for.

  Also, please explain: how do I issue the revision diff (e.g. bzr diff
  -r1306 setup.py) in the correct quilt format
