Subject: wc output padding differs when "-" is in the file list

It seems that whenever STDIN is involved the results padding reverts to the
BSD-style 7/8 padding. When files are given as input (excluding STDIN) the
padding reflects the width of the largest count. When files are given as
input and one of these is "-", the padding reverts again to the BSD 7/8
padding.
