Crash when typing something ending on : in shell

[nalquas]

When entering sys: or user: in the Homegirl Shell, the shell (correctly?) responds with Unknown command sys: or Unknown command user:.
However, when entering anything else ending with a :, e.g. hello:, Homegirl crashes with the following terminal output:

Powering on..

I suppose this falls under undefined behaviour (as you're supposed to change drives using cd), but I often find myself accidentally trying to change drives this way (similar to how you just type C: in a DOS prompt).

Yea, I think I encountered this bug when I developed it.. Now the project is pretty much discontinued, so I'm probably not going to fix this bug anytime soon..
