Support Bash

[erikw]

It would be great if this plugin would additionally support bash. Even though zsh is the default shell for me, at times I need to jump back to a bash session. I have configured my zsh and bash to share the greatest common intersection of config so they work practically the same for me.

Benefits:

• Support use case for those, like me, need to switch between zsh and bash
• But even more importantly, the potential user base becomes a lot larger by supporting bash too!
