Flush input before reading it

To avoid that, for example, a double enter confirms the default choice twice.

Sadly doesn't seem to work:

There's no good way to do it, apparently. I'd probably have to fuck around with fnctl in C.

[Guldoman]

Would something like fseek(stdin,0,SEEK_END); work?

[adamharrison]

Nope.

[adamharrison]

I think this is out of scope, honestly. Do other package managers do this?

[Guldoman]

Yeah, see https://gitlab.archlinux.org/pacman/pacman/-/blob/e3dc296ba35d5039775c6e53decc7296b3bce396/src/pacman/util.c#L183.

[adamharrison]

Oh, ok. That's easier than expected. Will implement.
