Double-column characters in insert mode

[Gunnar Ritter]

Hi,

when a double-width character is printed in insert mode, characters
that follow are not shifted for enough positions to the left. That
is, when the command

printf '%b\n' '0123456789\b\b\b\b\b\033[4h＠\033[4l'

is run, rxvt-unicode 4.1 eats the ‘5’ and prints

01234＠6789

instead of the correct

01234＠56789
