Brad King 59f6f383e9 Warn on set(PARENT_SCOPE) at top scope
Previously we silently ignored such calls and set nothing.  The commit
"Initialize directory scope with closure of parent" inroduced a bad test
for the top scope.  This commit fixes the test to avoid dereferencing a
null pointer, and adds a warning when the case is encountered.
