heuristic determination of day vs month in date/time input.  Add the
ability to specify that input is interpreted as yy-mm-dd order (which
formerly worked, but only for yy greater than 31).  DateStyle's input
component now has the preferred spellings DMY, MDY, or YMD; the older
keywords European and US are now aliases for the first two of these.

The third choice is allowed in case the assign_hook wants to return a
"canonical" version of the new value. For example, the assign_hook for
datestyle always returns a string that includes both basic datestyle and
us/euro option, although the input might have specified only one.
datestyle always returns a string that includes both output and input
datestyle options, although the input might have specified only one.
If a show_hook is provided, it points to a function of the signature
