Hmph. Looks like a mild-enough middle ground, I guess. As
parse_sort_string() is private for "git tag" implementation, I
actually would not mind if we taught a bit more context to it and
phrase its messages differently. Perhaps something like this, where
the config parser will tell what variable it came from with "var"
and the command line parser will pass NULL there.
static int parse_sort_string(const char *var, const char *value, int *sort)
{
...
if (strcmp(value, "refname")) {
if (!var)
return error(_("unsupported sort specification '%s'"), value);
else {
warning(_("unsupported sort specification '%s' in variable '%s'"),
var, value);
return -1;
}
}
*sort = (type | flags);
return 0;
}

Yup.
