[patch] Correct origin calculation of command line window in TUI mode

[Balazs Kezes <rlblaster@gmail.com>]

The locator's (a small bar between source and command window) origin (the first
row's index) is not updated in tui_resize_all and this outdated data is used to
calculate the command window's origin. This patch fixes this by updating it.
