While in wxUniv the year control can't +show all 4 digits, in wxMsw it show almost twice as +much. Instead the year should use it's best size and be +left aligned to the calendar. Just in case the month in +any language is longer than it has space in the +calendar it is shortend.This way the year always can +show the 4 digits. + +This patch relies on the fact that a combobox has a +good best size implementation.
