EOF/EOT gets surpressed when retreiving from stdin

[glibg10b]

$ grip -
 * Serving Flask app "grip.app" (lazy loading)

Ctrl+Z:

      0 [sig] bash 892! sigpacket::process: Suppressing signal 18 to win32 process (pid 1844)

Ctrl+D does nothing. There is no way to enter EOF, so it's impossible to retrieve input from the user with $ grip -. $ echo test | grip - does work correctly, however.

This could just be a Git Bash bug, but I think you should add an alternative way to pass EOF.
