  Fix time.strptime's %U support.  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).

  Remove specific mention of my name and email address from modules.  Not really
  needed and all bug reports should go to the bug tracker, not directly to me.
  Plus I am not the only person to have edited these files at this point.

........
  r53605 | brett.cannon | 2007-01-30 22:34:36 +0100 (Tue, 30 Jan 2007) | 8 lines

  No more raising of string exceptions!

  The next step of PEP 352 (for 2.6) causes raising a string exception to trigger
  a TypeError.  Trying to catch a string exception raises a DeprecationWarning.
  References to string exceptions has been removed from the docs since they are
  now just an error.
