[PATCH] rebase--interactive: do not use one-or-more (\+) in sed.

[Junio C Hamano <gitster@pobox.com>]

This is a continuation of the other one to avoid one-or-more operator
in sed.  At the same time, it actually tightens error checking,
because the numbers in the squash messages are not padded with
leading zero and cannot begin with 0.

With this, I think we do not have any more use of one-or-more
(\+) in sed scripts.
