Frederik Gladhorn 52f859604d Accessibility: Improve line boundary helper functions
These functions are supposed to make it easy for third parties (and
QLineEdit) to implement the textAt/Before/AfterOffset functions.
Before the functions were ignoring newlines completely and thus only somewhat
useful.
