Why append the underscore here if there is a separate variable tracking whether it should be?

The variable tracks whether the underscore is added by viper (legacy behaviour) or by user.
The rest of the code does not bother whether the envPrefix was modified by viper or not.

I'm not sure I like the name StrictEnvPrefix.
Something like RawEnvPrefix or BareEnvPrefix might sound better.
An alternative I can imagine is a separate option called EnvPrefixWithDelimiter (deprecating any current options).
cf. #1546
I didn't get to test with a sub parser. Hint welcome.
