[PATCH] ident: remove unused author_ident_sufficiently_given()

[Junio C Hamano <gitster@pobox.com>]

A pair of functions {author,committer}_ident_sufficiently_given()
were created to replace user_ident_explicitly_given() in d6991ceedc
(ident: keep separate "explicit" flags for author and committer,
2012-11-14).

But author_ident_sufficiently_given() is never used in our history.
We only check if committer ident is sufficiently given and use it to
nudge the user to set user.{name,email} configuration variables.

Remove the unused author_ident_sufficiently_given() function.
