VGA cursor sometimes not displaying #4

Closed apsun closed 7 years ago

When typing on the last line of the terminal or on the second/third terminal screens, the cursor disappears. It comes back if you type some characters and then delete them with backspace.

Fixed in r9659. Turns out that we can't just memset the VGA memory to all zeros, since the attrib/char (not sure which, maybe both) also affects the visibility of the cursor. Instead we now memset empty regions to ' ' + ATTRIB.
