[patch #3596] Sort directories before files in "ls"

[Francesco Montorsi]

Follow-up Comment #3, patch #3596 (project coreutils):

I've added to this tracker a new patch which should address all issues raised
by Eric Blake.

The only thing left out are systems without dirent.d_type: a stat for each
file isn't going to be too slow ?
Maybe that for those systems without dirent.d_type, it's better to just not
implement this option....

Please let me know if something needs to be changed.
Francesco


NOTE1: symlinks to directories are treated as simple files.

NOTE2: I couldn't think of any long option which begins with an unused char;
so I have used the -e option together with the long option
--group-directories
