[PATCH v2 0/4] Automatic transfer encoding for patches

This series introduces an "auto" value for git send-email --transfer-encoding that uses 8bit when possible (i.e. when lines are 998 octets or shorter) and quoted-printable otherwise; it then makes this the default behavior. It also makes --validate aware of transfer encoding so it doesn't complain when using quoted-printable or base64.

Changes from v1:
* Update commit messages to refer to RFC 5322.
* Add a missing space.
* Remove the needless capture of stderr.
* Define "suitable transfer encoding".
* Invert test to better capture failures.
* Wrap --validate code in an if block instead of returning early.
* Update documentation to reflect correct, modern RFC.
