non-fixed width fonts like Lucida Grande render the Calendar buffer unreadable/unusable; specifically, the dates [numerals] don't line up properly under the days ['Su', 'Mo'... 'Sa']
Is this a known fact?
Perhaps a fixed-width 'calendar-face' should be added in org-mode to handle this?
I don't know lisp to create such a calendar-face and perhaps a calendar-mode hook that would apply it
