switch to raw mode

add pledge

bind arrow up/down

add cd up/down and home

zero the whole argv array to avoid surprises

rewrite spawn to use varargs it's seems neater than packing an array on the spot, we just do that inside spawn before calling execvp. If we get too many arguments, just abort. This also changes how the forking is handled: I set RVSEL only for the child and call disable_handlers() and endwin() preemptively to avoid possible races with our children.

pedantic prototypes

const-ify message fmt string
