Jeff King 94425552f3 ident: do not ignore empty config name/email
When we read user.name and user.email from a config file,
they go into strbufs. When a caller asks ident_default_name()
for the value, we fallback to auto-detecting if the strbuf
is empty.

That means that explicitly setting an empty string in the
config is identical to not setting it at all. This is
potentially confusing, as we usually accept a configured
value as the final value.
