Junio C Hamano c01cdde186 Merge branch 'jk/maint-send-email-compose'
* jk/maint-send-email-compose:
  send-email: rfc2047-quote subject lines with non-ascii characters
  send-email: specify content-type of --compose body

Conflicts:

	t/t9001-send-email.sh

Due to 065096c (git-send-email.perl: Handle shell metacharacters in
$EDITOR properly, 2008-05-04) which is a backward incompatible change (but
it makes handling of EDITOR consistent with other parts of the system),
the test script t9001 had to be adjusted.

# Ported to support git "mbox" format files by Ryan Anderson <ryan@michonline.com>
#
# Sends a collection of emails to the given email addresses, disturbingly fast.
#
# Supports two formats:
# 1. mbox format files (ignoring most headers and MIME formatting - this is designed for sending patches)
# 2. The original format support by Greg's script:
# first line of the message is who to CC,
# and second line is the subject of the message.

git-send-email [options] <file | directory>...
Options:
--from Specify the "From:" line of the email to be sent.
--to Specify the primary "To:" line of the email.
--cc Specify an initial "Cc:" list for the entire series
of emails.
--cc-cmd Specify a command to execute per file which adds
per file specific cc address entries
--bcc Specify a list of email addresses that should be Bcc:
on all the emails.
--compose Use \$GIT_EDITOR, core.editor, \$EDITOR, or \$VISUAL to edit
an introductory message for the patch series.
--subject Specify the initial "Subject:" line.
Only necessary if --compose is also set. If --compose
is not set, this will be prompted for.
--in-reply-to Specify the first "In-Reply-To:" header line.
Only used if --compose is also set. If --compose is not
set, this will be prompted for.
--chain-reply-to If set, the replies will all be to the previous
email sent, rather than to the first email sent.
Defaults to on.
--signed-off-cc Automatically add email addresses that appear in
Signed-off-by: or Cc: lines to the cc: list. Defaults to on.
--identity The configuration identity, a subsection to prioritise over
the default section.
--smtp-server If set, specifies the outgoing SMTP server to use.
Defaults to localhost. Port number can be specified here with
hostname:port format or by using --smtp-server-port option.
--smtp-server-port Specify a port on the outgoing SMTP server to connect to.
--smtp-user The username for SMTP-AUTH.
--smtp-pass The password for SMTP-AUTH.
--smtp-ssl If set, connects to the SMTP server using SSL.
--suppress-cc Suppress the specified category of auto-CC. The category
can be one of 'author' for the patch author, 'self' to
avoid copying yourself, 'sob' for Signed-off-by lines,
'cccmd' for the output of the cccmd, or 'all' to suppress
all of these.
--suppress-from Suppress sending emails to yourself. Defaults to off.
--thread Specify that the "In-Reply-To:" header should be set on all
emails. Defaults to on.
--quiet Make git-send-email less verbose. One line per email
should be all that is output.
--dry-run Do everything except actually send the emails.
--envelope-sender Specify the envelope sender used to send the emails.
--no-validate Don't perform any sanity checks on patches.
