tty vt: Fix a regression in command line edition
The commit 81732c3b2f
("Fix line garbage in virtual console on command line edition")
made a regression with some machines: some characters were not erased
after line edition.
This patch adjusts the number of moved characters and the size of the
region to be updated.
