simplify dispatch_stdio
just call redraw_tab instead of re-implementing it in-place. This also fixes a bug with cmd_tab_{next,previous} where the body wasn't updated.
simplify wrap_page
reuse the line_prefixes table
add "faces"
move line styles to a central place.
implement cmd_{beginning,end}_of_buffer
to do that, refactor redraw_tab and split redraw_body out of it
1X input, load/edit current URL
