[Python-checkins] python/dist/src/Lib urllib2.py,1.42,1.43

> For reverting a complex checkin, you can generate a reverse delta:
>     cvs diff -r 1.43 -r 1.42 urllib2.py > revert.diff
>     patch urllib2.py revert.diff
>     cvs ci -m "Revert to 1.42" urllib2.py

Note that you can skip a step (and so avoid a chance to make a mistake) by
reverting directly during an update, replacing the first two lines with:

    cvs up -j 1.43 -j 1.42 urllib2.py

As in Raymond's example too, the order in which the revision arguments
appear is vital.
