submodule summary: do not shift a non-existent positional variable
When "git submodule summary" is run without any argument, we default to compare the state of index with the HEAD, but tried to shift out $1 that does not exist (and worse yet, we didn't use it). Signed-off-by: Junio C Hamano <gitster@pobox.com>
