# A much faster implementation of git_status_shortcuts() in ruby
# (bash: 0m0.549s, ruby: 0m0.045s)
#
# Last line of output contains the ordered absolute file paths,
# which need to be extracted by the shell and exported as numbered env variables.
#
# Processes 'git status --porcelain', and exports numbered
# env variables that contain the path of each affected file.
# Output is also more concise than standard 'git status'.
#
# Call with optional <group> parameter to just show one modification state
# # groups => 1: staged, 2: unmerged, 3: unstaged, 4: untracked
