[issue18039] dbm.open(..., flag="n") does not work and does not give a warning

[R. David Murray]

R. David Murray added the comment:

Isn't this change going to cause unexpected data loss for (possibly mythical) people depending on the existing behavior?  At an absolute minimum it needs an entry in the What's New porting section, but I'm wondering if a deprecation period is more appropriate.
