[issue9608] Re-phrase best way of using exceptions in doanddont.rst

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

Doc/howto/doanddont.rst is the source for
Python HOWTOs: Idioms and Anti-Idioms in Python
Moshe Zadka original author (added as nosy)

The gist of the patch is to clarify that using 'with' is best, not the non-with version that is currently called  both 'best' and 'not very good'. I agreed that the current version is confusing and the patch or something like it should be applied.

Floris: 2.6 is closed to non-critical patches. 3.3 is for patches that cannot be applied sooner.
