Log Message:
Fix out of bounds reads/writes after movetext() cheats

The calculation of the rows before/after a buffer split from movetext()
was off by one, which would result in reads/writes after the allocated
vmem under very specific circumstances.

The most obvious case was from a clear screen after changing the font
configuration on a screen that had scrolled.

Should fix ticket 222, and maybe 223.
