# Description: Add git status column to detail mode. Provides additional
# command line flag -G which will render the git status
# column also in normal mode. nnn.vim users may consider
# adding `let g:nnn#command = 'nnn -G' to their vim config.
#
# Dependencies: libgit2
#
# Authors: @crides, Luuk van Baal
