pointer variables in the options table or in option tables for various drivers.
For debugging output, it is useful to be able to find the name of the option
which is currently being processed. This function finds it, if it exists, by
-searching the table(s).

Arguments: a value that is presumed to be in the table above
Returns: the option name, or an empty string
