Subject: [PATCH] Change `||` to `&&` for whether MSYS is a tty

The MSYS terminal appears to create pipes with the name `msys-` but *don't*
contain `-pty`, so this changes the `||` logic to `&&` to ensure that the logic
here doesn't fire for MSYS terminals where piping is used to erroneously
diagnose a stdio stream as a tty.

Closes #23
