I suggested git_config_die_linenr(key, linenr), and I now realize it
should take the value too.

You're suggesting git_config_die_exact(key, value). Is it a typo that
you forgot the line number, or is it intentional? If intentional, I
don't think it solves your issue:


There are two errors in this file, and you need to provide a line
number. key and value alone do not allow you to know which line the
error is. You can use a convention like "complain on the first value
equal to the argument", but I'm not sure that would always work. And
that seems backward to me to reconstruct the line number since the
function can be called from places where the line number is already
known (while iterating over the string_list for example).
