Improve UTF-8 handling on lines that are wider than the terminal,
in two respects:
1. During output in x_e_putc(), when counting display columns,
skip UTF-8 continuation bytes. Fixes backward movements that
cause horizontal scrolling.
2. After deleting characters, recalculate the last byte that fits
on the line.
Patch from <Anton dot Lindqvist at gmail dot com> on tech@.
