From 389824ffbe95c477ad605b56394798905ad13853 Mon Sep 17 00:00:00 2001 From: Qiu Shumin Date: Thu, 10 Sep 2015 03:08:56 +0000 Subject: ShellPkg: Fix Shell fail with redundant space following delay number. When boot from Shell we can use '-delay [num]' as optional data. If blank space exist after '[num]' Shell will fail. This patch add error handling to avoid this failure.
