Date parsing fails when an abbreviated month name is the wide month name + "."
This makes the abbreviated from longer than the wide form.
We have patched a few locales to be this way, including nl.
Here are some resulting test failures from TestDateFormatRoundTrip:
FAIL: fmt->parse failed, error U_ILLEGAL_ARGUMENT_ERROR, str=28 mei. 1817 06:00:00 in locale: nl
FAIL: fmt->parse failed, error U_ILLEGAL_ARGUMENT_ERROR, str=27 mei. 0421 12:46 in locale: nl
FAIL: fmt->parse failed, error U_ILLEGAL_ARGUMENT_ERROR, str=7-mei.-1511 21:42 in locale: nl_BE
FAIL: fmt->parse failed, error U_ILLEGAL_ARGUMENT_ERROR, str=7 mei. 3143 17:10 in locale: nl_NL
