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.
