Re: [PATCH v3 0/4] Factorize i18n

> This is a small series of i18n factorizations. Again the idea is to:
> 
>  * reduce the number of strings to translate
>  * make life easier for translators by removing constant parts of the
>    strings to translate
>  * uniformize the UI by using a type of message for the a given type of

> Changes since V1:
> 
>  * factorize checks of more than 2 incompatible options into dedicated
>    functions which list all the incompatible options present on the command
>    line
> 
> Changes since V2:
> 
>  * switch to tab size 8
>  * rename die_if* to die_for*
>  * make 3 arg check a call to 4 arg check
>  * switch another part to die_for_incompatible_opt4
