I don't understand why a second line in the keyboard is visible now where
it wasn't before. That whole aspect has unclear desires. What exactly do
I want to happen on newlines?

extremely threadbare null-pointer protection
...
This protects us from reading null arrays, but not null structs.
It also doesn't protect us from writes to address 0 itself.
It is also incredibly unsafe. According to https://wiki.osdev.org/Memory_Map_(x86) ,
address 0 contains the real-mode IVT. Am I sure it'll never ever get used
after I switch to protected mode? I really need a page table, something
minimal to protect the first 4KB of physical memory or something.
I wonder what other languages/OSs do to protect against really large struct
definitions.

bugfix: initialize gap buffers before using them
...
I keep running into one hole in Mu's memory-safety since dropping the Linux
dependency: null pointers no longer error when dereferenced. Here the problem
manifests as aliasing: lots of gap buffers share the same exact data near
address 0, because it was never initialized.
