[PATCH 17/19] list-files: add -F/--classify

[Nguyễn Thái Ngọc Duy]

This appends an indicator after the file name if it's executable, a
directory and so on, like in GNU ls. In fact append_indicator() is a
rewrite from get_type_indicator() in coreutils.git commit
7326d1f1a67edf21947ae98194f98c38b6e9e527.
