Instead of using the injected builtins feature of gettext, import the
name.  Then both pyflakes and human readers of the code will know what's
going on.

    from gettext import gettext as _

Title:
  Recognize _("text") from gettext.install(...)

Status in Pyflakes:
  Won't Fix

Bug description:
  gettext module provides convenience function gettext.install() that
  injects a callable _ [single underscore] into builtins, so that
  internationalized code can be written like this:

  print _("text")

  pyflakes reports every _ as undefined symbol.

  moreover since it is injected in builtins, all imported modules have
  that symbol, thus the following works:

  # main.py
  import gettext
  import somemod
  gettext.install(...)

  #somemod.py
  print _("text")

  I'm not sure what sort of heuristic could be used to recognize _() when pyflake checks somemod.py.
  Perhaps a command line argument for extra builtins?
