Let `enter` output `git status`

[lode]

From https://github.com/thoughtbot/gitsh I loved the feature of using enter to get the current git status. It feels very natural and a handy shortcut.

(I do like how most commands, i.e. also arrow keys, are given to the normal systems prompt, that should not change in its base.)

I don't think that this is technically possible. It works in gitsh because that is a separate executable program, and can thus can handle enter separately. However, git-sh is just a set of shell aliases and extensions build on top of bash, and afaik bash does not offer a way to do this other than PROMT_COMMAND, which as the name suggests actually executes on every command (whether it was empty or not).
