Although the day is optional according to the regexp.  I would
definitely like to have the regexp with the space optional as well as
there are cases where I want to type the date in directly (not in org
mode for whatever reason).  In those cases, it is easy to type
2011-01-01 or whatever but it's not necessarily trivial to determine the
day of the week...

Actually, interesting thought experiment: does org actually do any
consistency checks, comparing the date and the day of the week?
