Ensight reader crashes with valid case files that have filename numbers on more than a single line
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Since the Ensight reader does not check the return values from sscanf(), it doesn't notice when its assumptions fail. One such failure occurs when the filename numbers do not occur on a single line immediately following the "filename numbers:" introducer. This results in very incorrect values for the filenameNum and/or useless animation values.
The attached patch solves the problem.
