Update of /cvsroot/python/python/nondist/sandbox/datetime
In directory sc8-pr-cvs1:/tmp/cvs-serv4656
Modified Files:
	doc.txt 
Log Message:
Documented what the Python implementation actually does for
date +/- timedelta. The C code doesn't yet match, and these behaviors
aren't yet tested.
The Python implementation also has a funky class attribute,
date.timedelta_class, which is used to construct the result of
date-date; it's unclear what the point is, the C implementation
doesn't have this, and it's not tested.

 timedelta + date1 -> date2
 date2 is timedelta.days days removed from the date1, moving forward
! in time if timedelta.days > 0, and date2 - date1 == timedelta.days
! after. timedelta.seconds and timedelta.microseconds are ignored.
! OverflowError is raised if date2.year would be smaller than MINYEAR
! or larger than MAXYEAR.

 timedelta + date1 -> date2
 date2 is timedelta.days days removed from the date1, moving forward
! in time if timedelta.days > 0, or backward if timedetla.days < 0.
! date2 - date1 == timedelta.days after. timedelta.seconds and
! timedelta.microseconds are ignored. OverflowError is raised if
! date2.year would be smaller than MINYEAR or larger than MAXYEAR.

 isn't quite equivalent to date1 + (-timedelta), because -timedelta
 in isolation can overflow in cases where date1 - timedelta does
