Re: [PATCH v4] send-email: --batch-size to work around some SMTP server limit

xiaoqiang zhao [off-list ref] writes:

Some email servers (e.g. smtp.163.com) limit the number emails to be
sent per session(connection) and this will lead to a faliure when
sending many messages.

Teach send-email to disconnect after sending a number of messages
(configurable via the --batch-size=<num> option), wait for a few
seconds (configurable via the --relogin-delay=<seconds> option) and
reconnect, to work around such a limit.

Also add this two configure option for git config command.

s/configure/configuration/; "for git config command" is better left
unsaid (too obvious).

Note:
   Re-authentication will happen every $<batch-size> messages, so it
will be much more acceptable if you use some form of credential helper
(e.g. the 'sendemail.smtppass' config option), otherwise you will have
to retype password every time when asked.

I think this deserves to be in the end-user documentation (i.e. the
part of your patch that updates Documentation/git-send-email.txt).

Other than that, looking good ;-)

Thanks.
