Basically rewrote the algorithm to be more generic so that one only has to shift certain values based on whether the week was specified to start on Monday or Sunday. Cut out a lot of edge case code compared to the previous version. Also broke algorithm out into its own function (that is private to the module). Fixes bug #1643943 (thanks Biran Nahas for the report). ........ r53570 | brett.cannon | 2007-01-26 00:30:39 +0100 (Fri, 26 Jan 2007) | 4 lines Remove specific mention of my name and email address from modules.
