Hello
Currently, GNU coreutils doesn't have any test verifying the actual
output of ls --dired.
It should generate a list of position (pairs).
//DIRED// 73 82 142 152 ...
The attached patch creates 2 files and one directory and verify that we
can find their names using the position.
Cheers,
Sylvestre
