This is a feature, and a needed one. Understand that a space is
a legal filename character in a file under Unix:
br1.chatusa.com:root{119}# touch "X "
br1.chatusa.com:root{120}# touch "X "
br1.chatusa.com:root{122}# ls -lag X*
-rw-r--r-- 1 root wheel 0 Apr 11 15:42 X
-rw-r--r-- 1 root wheel 0 Apr 11 15:43 X
If tar was to strip off spaces, even trailing or leading spaces from
an exclude file list it would not allow full functionality and then
we would have a bug.
