rustup-init leaves user with colored terminal

(If this doesn't belong here, please tell me which repo to move it to, thanks!)

Problem

rustup's setup script, rustup-init, leaves the user with a colored terminal when exiting interrupted.

Steps

1. Execute rustup-init
2. At the first prompt, interrupt by Ctrl-C
3. User's shell is now red.

Possible Solution(s)
Check the interrupted-exit code maybe? Make sure that the color is reset before exiting (Since ^C is displayed in red)

Start at the rustup-init entry point and reproduce the Windows terminal state by interrupting the first prompt with Ctrl-C. Trace the interrupted-exit path and verify that the terminal color is reset before exit; done means the shell is no longer red after the interruption.
