Colin Watson has proposed merging lp:~cjwatson/launchpad/no-xrange into 
lp:launchpad with lp:~cjwatson/launchpad/range-iterator as a prerequisite.

Commit message:
Replace xrange with range, since xrange doesn't exist in Python 3.

Requested reviews:
  Launchpad code reviewers (launchpad-reviewers)

For more details, see:
https://code.launchpad.net/~cjwatson/launchpad/no-xrange/+merge/337044

Long, but doesn't really seem worth splitting up as it's almost all just 
s/xrange/range/g.  The only complication is that there are a couple of places 
that really do want an iterator rather than a list, and range returns a list in 
Python 2, so in those cases I went for iter(range(...)) which works in both 
versions of the language.
-- 
Your team Launchpad code reviewers is requested to review the proposed merge of 
lp:~cjwatson/launchpad/no-xrange into lp:launchpad.
