None of the above need to be in the e-mail body (the first one must
not be in the e-mail body, and the other three are redundant).

Hmph, the only change I see relative to the version in the message
you are responding to is reversion of the proposed commit log
message rewrite I did, and missing sign-off from you, and the latter
of which matters most.

I'd keep the one queued on 'pu' 73ffac3b (git-svn: fix termination
issues for remote svn connections, 2013-09-03) for now.

Thanks.
