The original code as below intend to set the character
before last column to CHAR_NULL.
Line[(LastCol % (ARRAY_SIZE (Line) - 1)) - 1] = CHAR_NULL;
But when LastCol % (ARRAY_SIZE (Line) - 1)) equals to 0,
Line[-1] is modified.
We should change to code as below:
Line[(LastCol - 1) % (ARRAY_SIZE (Line) - 1)] = CHAR_NULL;

Please ignore the mail titled with:
[edk2] Recall: [PATCH] Shellpkg/editor: Fix a bug that may modifies Line[-1]
Since I received a notification that my previous r-b mail was rejected by
the edk2-devel mailing list. Sorry for the noise.
Best Regards,
Hao Wu
