commit 97ed2ce08560d1446c175a4a2e025762a1424e9a
Author: Nick Mathewson <nickm at torproject.org>
Date:   Mon Jan 2 12:16:57 2017 -0500

    Unindent long-misindented blocks.
    
    We switched these to be "if (1) " a while back, so we could keep
    the indentation and avoid merge conflicts.  But it's nice to clean
    up from time to time.
