[issue30302] Improve .__repr__ implementation for datetime.timedelta

[R. David Murray]

R. David Murray added the comment:

If the docstring changes incorporate changes from this PR, I'd keep them in a single PR myself.  If not, two PRs would make review easier.  On the other hand, if haypo is volunteering to do the review, do whatever he wants :)
