‘Know which branch we’re on’ on Ubuntu 16

[Simon Albrecht]

Hello,

finally I’ve managed to get Ubuntu 16.04 working, and copied all of my 
previous home directory including .bashrc. However, the ‘export PS1’ 
trick suggested in 
<http://lilypond.org/doc/v2.19/Documentation/contributor/setting-up#configuring-git> 
with the following line in .bashrc:

export PS1="address@hidden \w\$(__git_ps1)$ "

doesn’t seem to work the same anymore: upon any command I execute in the 
terminal I get an error message ‘__git_ps1: command not found’. Can 
anyone give me a hint how to update this?

Best, Simon
