mail/fetchmail*: bugfix update to 6.4.39

* When a server offers STARTTLS although the connection is already wrapped
  in TLS, fetchmail would issue a bogus "WARNING: server offered STARTTLS but
  sslproto '' given." (or STLS for POP3).  In situations where we wrap the
  connection in TLS, suppress the warning. Reported by Mike Pope.

* If fetchmail was running localized, generate an error e-mail message locally,
  and if the selected translation would require the Subject: line to wrap
  inside an RFC-2047 encoded word (=?UTF-8?Q?...?=), the wrapped encoded-word
  was not indented, thus not marked as a continuation line.
