   DESCRIPTION
     Copy ref key and check for null parts in it.
+    Depending on the nullability and conversion problems this function
+    recognizes and processes the following states :
+      1. Partial match on top level. This means IN has a value of FALSE
+         regardless of the data in the subquery table.
+         Detected by finding a NULL in the left IN operand of a top level
+         expression.
+         We may actually skip reading the subquery, so return TRUE to skip
+         the table scan in subselect_uniquesubquery_engine::exec and make
+         the value of the IN predicate a NULL (that is equal to FALSE on
+         top level).
+      2. No exact match when IN is nested inside another predicate.
+         Detected by finding a NULL in the left IN operand when IN is not
+         a top level predicate.
+         We cannot have an exact match. But we must proceed further with a
+         table scan to find out if it's a partial match (and IN has a value
+         of NULL) or no match (and IN has a value of FALSE).
+         So we return FALSE to continue with the scan and see if there are
+         any record that would constitute a partial match (as we cannot
+         determine that from the index).
+      3. Error converting the left IN operand to the column type of the
+         right IN operand. This counts as no match (and IN has the value of
+         FALSE). We mark the subquery table cursor as having no more rows
+         (to ensure that the processing that follows will not find a match)
+         and return FALSE, so IN is not treated as returning NULL.
+
 
   RETURN
-    FALSE - ok, index lookup key without keys copied.
-    TRUE  - an error occured while copying the key
+    FALSE - The value of the IN predicate is not known. Proceed to find the
+            value of the IN predicate using the determined values of
+            null_keypart and table->status.
+    TRUE  - IN predicate has a value of NULL. Stop the processing right there
+            and return NULL to the outer predicates.
