I don't see any inconsistency.  'insert' is a much more
general-purpose primitive than indent-to.  It would be dead wrong for
each insertion to inherit the properties.

indent-to is different: when you indent text, you supposed want the
whitespace to use the same face, for example.  Think about it.
