Clean PS1 (with current git branch displayed)

Lambda-PS1

#
# This is a simple, clean PS1 with current git branch displayed.
# How will look like:
#
# λ ~/home/project (master) 
#
# NOTE: You may have to configure your terminal to support UTF-8 Unicode (so λ will displayed correctly)


function parse_git_branch () {
  git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
