submodule: document "sync --recursive"

charlesmchen · gitster · commit 9393ae79c9b4 · 2014-06-13T15:00:17.000-07:00
The "git submodule sync" command supports the --recursive flag, but
the documentation does not mention this.  That flag is useful, for
example when a remote is changed in a submodule of a submodule.
