Trying to follow instuctions on readme.
When I try to use aftman to add a tool I get error messages like so:
$ aftman.exe add rojo-rbx/rojo
Tool rojo-rbx/rojo has never been installed before. Install it? [y/n] Aftman error: Incorrect function. (os error 1)

$ aftman install
Tool rojo-rbx/rojo has never been installed before. Install it? [y/n] Aftman error: Incorrect function. (os error 1)

Super strange, I've never heard of an "Incorrect function" OS error! Something to look into.

Seems likely related to console-rs/console#35.

had the same problem running it through git bash. powershell worked fine though.
