rebase -i: use full onto sha1 in reflog

Michael J Gruber · gitster · commit 1af221ef5cb8 · 2012-08-10T09:41:28.000-07:00
'git rebase' uses the full onto sha1 for the reflog message whereas 'git
rebase -i' uses the short sha1. This is not only inconsistent, but can
lead to problems when the reflog is inspected at a later time at which
that abbreviation may have become ambiguous.

Make 'rebase -i' use the full onto sha1, as well.
