Hi Ted,

Yes, definitely just whitespace.  But i don't understand why you are
getting this behavior.  I tried both with the master branch of e2fsprogs
and the tagged commit of v1.45.2 and on both occasions the test succeed
in my system.  For sure I can use filter_spaces but I'm puzzled why I
can't reproduce this.
