[PATCH 2/3] octopus: reenable fast-forward merges

From: Stephen Boyd <hidden>
Date: 2016-06-15 22:47:54
Subsystem: the rest · Maintainer: Linus Torvalds

The fast-forward logic is never being triggered because $common and
$MRC are never equivalent. $common is initialized to a commit id by
merge-base and MRC is initialized to HEAD. Fix this by initializing
$MRC to the commit id for HEAD so that its possible for $MRC and
$common to be equal.

Signed-off-by: Stephen Boyd <redacted>

Found this while making tests up for part 1 of this series.
