[PATCH 2/2] ident: make the useConfigOnly error messages more informative

[Marios Titas <redneb@gmx.com>]

The env_hint message applies perfectly to the case when
user.useConfigOnly is set and at least one of the user.name and the
user.email are not provided. Additionally, use a more descriptive error
message when that happens.
