minor issue: Should we create a new line if 'http' is not the first non-comment
character?

// http://...
  does not make a new line, but 
// See spec: http://
  should

[ddorwin, 2013/09/07 04:31:43]

Should we combine this if with the one above?

If that's too messy, does Python support else if? Either way, it's clearer that
this block is unrelated to the rest of the "else" and we get rid of the
continue.

There are a lot of cases here that aren't handled; i.e. http may not even be in
a comment.  Comments may be block or inline too, so that makes detection tricky.
 I'd rather leave such cases alone until they need to be supported.

IMHO, Indent() should be removed in favor of clang-format integration. 
Obviating the need for whats sure to always be a partial subset of correct
indentation.

Done; though now space_break is always computed.
