Good point, I used to have a variable with a long name but it's gone, so I'll
condense the assignments.

Me neither. I opted for "opt" :-) because it's shorter and right now there is no
auto-completion for boot2 or loader prompts.

Two reasons:
(1) memtest seems to be tailored to a different purpose and it currently has a
maintainer whom I haven't consulted about any changes yet;
(2) [more important] original memtest86 has a peculiarity that it needs to be
loaded in conventional memory (first 640k) and that doesn't work very well with
our loader (yet); I have some ideas, but they need additional work, so memtest86+
was the lower-hanging fruit.
