the new form is
%0<width>s
where <width> is a positive integer
at most the <width> *trailing* characters of the string are printed
(it truncates from the head)
this form
%.<width>s
at most the <width> *leading* characters of the string are printed
(it truncates from the tail)
for example:
$ printf $'%.4s\n' 123456789
1234
$ printf $'%04s\n' 123456789
6789
this is handy when listing column limited data where the significant
info is in the tail (e.g., path names)
