Dylan Smith 1181bb762f richedit: Prevent copying PARAFORMAT2 fields from PARAFORMAT struct.
If a EM_SETPARAFORMAT message is sent to the richedit control with bits
in the dwMask field that correspond to PARAFORMAT2 fields, then these
fields should be ignored.  Instead data was copied from outside of the
structure.
