[PATCH 01/10] git-submodule.sh: create a "case" dispatch statement

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Create a "case/esac" dispatch statement at the end of git-submodule.sh
and move the contents of the trivial cmd_absorbgitdirs() function to
it.

This template will be expanded on in subsequent commits, but for now
we're moving the trivial "git submodule absorb-git-dirs" to it.
