Re: [PATCH] config.c: change the function signature of `git_config_string()`

OK, it seems I got convinced too quickly by Junio ;-). The function
produces a char * that can be modified, but it also receives a value,
and the function should keep the "const" to allow passing "const char
*".

Don't blame me. I never suggested to touch that existing function,
with existing call sites.
