Michael Witten 8a7c56e159 git-send-email: Better handling of EOF
Before, when the user sent the EOF control character, the
prompts would be repeated on the same line as the previous
prompt.

Now, repeat prompts display on separate lines.

# 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-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.
