highlight: convert text to local before passing to pygmentize

Example case:
Display file written in iso-8859-1 with currten HGENCODING utf-8.
At the moment only an Error page appears because pygmentize
chokes on the replacement chars.

Alternatives:
1) Turn off highlighting and avoid UnicodeDecodeError
   for files that are not in HGENCODING.
2) [this patch] use util.tolocal to display these files.

Alternative 2) seems ok, as this only concerns display and
readability.

highlight.
