[PATCH] qemu: reset more state after CR/LF

[Jim Paris <jim-XrPbb/hENzg@public.gmane.org>]

After receiving CR or LF on the monitor, reset term_last_cmd_* as
well.  This matches the setup that is done by term_show_prompt(), and is
for the case when readline_start() is not called before the next
readline_handle_byte().  Without this, unnecessary terminal escape
sequences will be printed by term_update() before the next prompt.

Avi, this goes along with 076e405adda6b47563e23ac24b57c8bb8ba55488,
"qemu: reset buffer pointers after CR/LF", which wasn't quite complete.
Thanks.
