Text included by way of literalinclude directives is too wide for the border in html mode

[DavidGriffith]

At least in the appendices when transcripts and game source are presented by way of literalinclude directives, the resulting box around the text is too narrow. Even though the transcripts and sources are all at 80 columns of width, some chunks of text are cut off at the right side when the document is compiled to HTML.

This can probably be fixed by increasing the page_width value of html_theme_options in conf.py.
