Suspect a whitespace issue with the parser.

Relevant line introduced in b091e8a: https://github.com/sunlightlabs/Capitol-Words/blame/master/parser/parser.py#L163

Expects titles to be a single line.

Encapsulating logic seems to be:

• Line indented 6 spaces starts with 'By ' + re_newspeaker
• Subsequent, optional lines indented 8 spaces
• New paragraph that does not match re_newspeaker

Should be attributed as 'recorder'
The previous line with 8 centered underscores is truncated to empty by clean_line().
