The problem I have with this is that the sign-off's are not bad, they
are by default indented by 'git show' or 'stg show' so checkpatch.pl
should handle the "default" formatting of git/stg and if there is
additional indenting not expected, then the sign-off's should be
considered bad.  If this option is added, then if there were "real"
problems with the sign-off, it would not be displayed.

Even doing this does not resolve the "false" warnings" that
checkpatch.pl produces regarding the sign-off's.
