Title:
  Warns after using a variable that was deleted in a conditional

Status in Pyflakes:
  New

Bug description:
  Consider this snippet:

      def f():
          x = 1
          if False:
              del x
          x

  It is entirely appropriate to use 'x' after that conditional, but
  pyflakes warns with "undefined name 'x'". Instead it should not warn
  at all.

  See http://bazaar.launchpad.net/~testtools-
  committers/testtools/trunk/view/head:/testtools/matchers.py#L789 for a
  real world example.
