Been using the same (more or less) on Fedora and RHEL for some time
myself, and yeah, its insanely helpful when working with git repos.

The main logic is part of the core git package in Fedora/RHEL, which
installs /etc/bash_completion.d/git. I'm not actually using full-blown
additional bash completion, so I'm sourcing that in via .bashrc, and
incorporating the necessary __git_ps1 into my already personally
customized PS1.

Full range of the relevant .bashrc bits I've added:

source /etc/bash_completion.d/git
export GIT_PS1_SHOWDIRTYSTATE=true
export GIT_PS1_SHOWUNTRACKEDFILES=true

# color prompt
BLUE='\[\033[01;34m\]'
GREEN='\[\033[01;32m\]'
BLACK='\[\033[00m\]'
YELLOW='\[\033[01;33m\]'
RED='\[\033[01;31m\]'
PS1='['$GREEN'\u'$BLUE'@\h '$RED'\W'$YELLOW'$(__git_ps1 " (%s)")'$BLACK']\$ '
export PS1
