Specify encoding of compose message. Default is the value of the
'sendemail.composeencoding'; if that is unspecified, UTF-8 is assumed.
+--transfer-encoding=(7bit|8bit|quoted-printable|base64)::
+ Specify the transfer encoding to be used to send the message over SMTP.
+ 7bit will fail upon encountering a non-ASCII message. quoted-printable
+ can be useful when the repository contains files that contain carriage
+ returns, but makes the raw patch email file (as saved from a MUA) much
+ harder to inspect manually. base64 is even more fool proof, but also
+ even more opaque. Default is the value of the 'sendemail.transferEncoding'
+ configuration value; if that is unspecified, git will use 8bit and not
+ add a Content-Transfer-Encoding header.
+
+--xmailer::
+--no-xmailer::
+ Add (or prevent adding) the "X-Mailer:" header. By default,
+ the header is added, but it can be turned off by setting the
+ `sendemail.xmailer` configuration variable to `false`.
