This PR fixes an issue with the padding of the size column when using -l and the folder contains more than one file. The output of ls -l before the change:

total 0
-rw-r--r-- 1 dho dho    0 Nov 30 15:29 c.txt
-rw-r--r-- 1 dho dho    0 Nov 30 15:51 d.txt

And after the change:

total 0
-rw-r--r-- 1 dho dho 0 Nov 30 15:29 c.txt
-rw-r--r-- 1 dho dho 0 Nov 30 15:51 d.txt

This is the same output as GNU ls produces.
