Subject: [PATCH] Move QEMU bug workaround from host wrapper to target init
 script.

(QEMU's bios inexplicably outputs the DEC private mode wordwrap disable
sequence from "man 4 console_codes", meaning typing off the right edge
of the screen just sits there overwriting the last character over and over.
This confuses all SORTS of stuff, such as bash's command line history
editing, and persists basically forever because nothing knows how to
undo it. Nope, "reset" leaves it, "stty" hasn't got a flag for it...
You've got to output the corresponding magic undo sequence.)
