   An 85-year injustice has been rectified at Poets' Corner in Westminster Abbey with the corrected spelling of one of the greatest of all literary names. Reader, it is finally Brontë, not Bronte. An amended memorial to Charlotte, Emily and Anne Brontë was unveiled on Thursday with added diaereses (two dots) that ensure people pronounce it with two syllables.
