In function InternalShellPrintWorker(), if the string in variable
'mPostReplaceFormat2' starts with character L'%', the following
expression:
*(ResumeLocation-1) == L'^' at line 2831
will read an undefined value before the starting of string
'mPostReplaceFormat2'.
This commit adds additional logic to avoid reading undefined content.
