[New-bugs-announce] [issue36232] Improve error message on dbm.open

[Marco Rougeth]

New submission from Marco Rougeth <marco at rougeth.com>:

If dbm.open is used with the flags 'r' or 'w' (read-only) to open a file that doesn't exist, it raises an exception with the message "need 'c' or 'n' flag to open new db". It'd be better to have a more explicit error message like "db file doesn't exist, use 'c' or 'n' flag to open new db".
