Subject: [PATCH] Fix inline formatting at beginning of paragraph

Paragraphs start usually when a non special character is entered in the
NONE state. Previous to this change, they were not starting until that
non-special character, meaning lines starting with formatting would have
a strange skew:

    <em><p>italics</em></p>

This patch encapsulates the "start a paragraph if it's NONE" and
triggers it for all inline formatting as well as non-special chars
