# Description: Add git status column to detail mode. Provides additional
# command line flag -G which will render the git status
2021-11-05 16:01:56 +00:00
# column also in normal mode. Vim plugin users may consider
# adding the -G flag to their command override.
# Compatibility patch for the namefirst patch.
