[PATCH] git-submodule summary: fix that some "wc" flavors produce leading spaces

[Johannes Sixt <j.sixt@viscovery.net>]

From: Johannes Sixt <johannes.sixt@telecom.at>

We print the number of commits in parentheses, but without this change
we would get an oddly looking line like this:

    * sm1 4c8d358...41fbea9 (      4):

Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at>

	How portable is this?
