[PATCH] send-email: Net::SMTP::starttls was introduced in v3.01 (Re: [BUG] git-send-email broken: Can't locate object method "starttls")

[Jonathan Nieder]

Subject: send-email: Net::SMTP::starttls was introduced in v3.01

We cannot rely on the starttls method being present in the copy
of Net::SMTP shipped with perl until v5.21.5~169 (Update libnet to
CPAN version 3.01, 2014-10-10).
