ui-blame: Allow syntax highlighting
Place file contents into a single block so that syntax highlighting can be applied in the usual fashion. Place the alternating color bars behind the file contents. Force the default syntax highlighting background to transparent. Signed-off-by: Jeff Smith <whydoubt@gmail.com> Reviewed-by: John Keeping <john@keeping.me.uk>
