Due to the way we run ls(1), through xargs(1), the leading whitespace
can change even when the setuid files haven't. To avoid displaying
these lines, we currently run diff(1) with the '-w' option. However,
this is probably not the ideal way to go; there is a very, very small
possibility for diff(1) to miss things is shouldn't. So, with the
leading space cleaned, we can revert to the '-b' option which is
"safer."
