Enhance the text backend to support configurable quote characters,

configurable emphasis characters, various other configurable bits
which have been marked FIXME in the code for a while, and also to
warn when a code paragraph line is too long (because that was the
only other thing labelled FIXME). Fallback options are implemented,
and defaults set accordingly. A UTF-8 text output file now looks
like proper UTF-8.
