Subject: [PATCH 2/3] merge-recursive: untangle double meaning of o->call_depth
Date: Sun, 7 Jul 2013 20:02:39 +0200 [thread overview]
Message-ID: <7e823a9faedf1980912628c3a3f083e26fb0c650.1373219466.git.trast@inf.ethz.ch> (raw)
In-Reply-To: <cover.1373219466.git.trast@inf.ethz.ch>
o->call_depth has a double function: a nonzero call_depth means we
want to construct virtual merge bases, but it also means we want to
avoid touching the worktree. Introduce a new flag o->no_worktree for
the latter.
