Use the same message when an invalid value is passed to a command line
option or a configuration variable.

Hi Jean-Noël

I think the factorization works well here. I think in the previous 
series you mentioned the possibility of creating macros for standard 
messages, reading this patch that or some standard functions like 
error_invalid_value() seem like a good idea to keep the messages 
consistent in the future.

Best Wishes

Phillip
