Subject: feed: Remove the for loop variable `e` for a clean namespace
X-Git-Tag: v3.0~19
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=e7035b663fdf0792a5125e90736f99e903b2f0be;p=rss2email.git

feed: Remove the for loop variable `e` for a clean namespace

Otherwise:

  >>> import rss2email.feed
  >>> print([x for x in dir(rss2email) if not x.startswith('_')])
  ['Feed', 'e']

which might confuse people ;).
