clear doesn't work on Git Bash

When I run `clear` using the `bash.exe` that's shipped with Git for Windows, the console doesn't clear in 0.4.0.0. The cursor's position is reset, but all of the text content remains. This worked in 0.3.1.0. Is there a way to alias `clear` to Ctrl+L?

**Edit: I also have issues when detaching from a tmux session. The screen contents aren't cleared.**
