Subject: [PATCH] Bug #12589928: MEMORY LEAK WHEN RUNNING
 SYS_VARS.SECURE_FILE_PRIV

This is the 5.1 version of the fix.

Need to free the memory allocated by the option parsing code for empty
strings when resetting the pointer to NULL.
No test case needed, as the existing ones already cover this path.
