Subject: feed: Add 'default' argument to Feed._html2text for HTMLParseError
X-Git-Tag: v3.7~3^2~1

feed: Add 'default' argument to Feed._html2text for HTMLParseError

This allows us to easily fall back on an unconverted string in the
event that the input HTML is malformed.  We already caught
HTMLParseError when converting HTML to plain test for non-html mail,
but we didn't catch it in Feed._get_entry_title.  Now we gracefully
handle the situation by treating the malformed HTML as plain text.
