Log Message:
-----------
Allow second and subsequent names in a qualified (dotted) name to be
ColLabel instead of just ColId --- that is, any keyword can appear after
a dot and it will be taken as an identifier. Fixes problems with names
that are okay as standalone function names but fail when qualified.
