Subject: submodule.c: refactor recursive block out of absorb function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A move and indentation-only change to move the
ABSORB_GITDIR_RECURSE_SUBMODULES case into its own function, which as
we'll see makes the subsequent commit changing this code much smaller.
