Yes, -I is a synonym for --iso-8601, but both options were deprecated in
2005 by commit 2c29ba03 (and hence undocumented).  One real fix would be
to start making this option output a warning, so that we can delete it.

Another would be to teach getdate.y how to parse 'T' as the separator
between date and time, so that we could reinstate the option (it was
deprecated because we feel badly about supporting an output format that
we can't reparse as an input format).
