it's one line ;) but i can understand your concern. would `git status -s -v` or `git status -s --show-branch` make sense?

i had one hash and two spaces at first, but as you said, two hashes look more lined up.

i used ... to make it look consistent with normal branch output, but i guess you are right. i changed it to `Initial commit on <branchname>

oh, i didn't know `git branch -v`. the cut&paste argument is really strong, so i totally agree with you and changed my code.
branch names and ahead/behind numbers appear now in green and red to match the output of `git branch -l`
here is the updated patch:
- initial commit is also printed when there is tracking information
(i still haven't managed to create a situation like that. `git branch
oldmaster; rm .git/refs/heads/master; git branch master --set-upstream
oldmaster` will reset branch master to oldmaster (a bug?))
- colors to match output of `git branch` (green: current, red: remote)
- output format is copy-pasteable, ahead/behind information is in the
same format as in `git branch -v`
- branch information is still printed by default, i have to look into
commandline option parsing first. i was thinking of `git status -v -b`
(as in `git checkout -b` to mean branch)
cheers, daniel

Subject: [PATCH] Show branch information in short output of git status
This patch adds a first line in the output of `git status -s`, showing which branch the user is currently on, and in case of tracking branches the number of commits on each branch.
