title: C style guide tips for a <80 char line
body: <p>I can't find many recommendations/style guides for
  C that mention how to split up lines in C so you 
  have less then 80 characters per line.</p>
  
  <p>About the only thing I can find is <a href="http://www.python.org/dev/peps/pep-0007/" rel="nofollow">PEP 7</a>,
  the style guide for the main Python implmentation
  (<a href="http://en.wikipedia.org/wiki/CPython" rel="nofollow">CPython</a>).</p>
  
  <p>Does a link exist to a comprehensive C style guide 
  which includes recommendations for wrapping? </p>
  
  <p>Or failing that, at least some good personal advive
  on the matter?</p>
  
  <p>P.S.: What do you do with really_long_variable_names_that_go_on_forever
  (besides shortening)? Do you put them on the left edge or let it spill?</p>
