Current implementation of QLineEdit uses the "edited" bit-field flag to prevent unnecessary emissions of editingFinished() when a line edit loses focus but its contents have not changed since the last time the signal was emitted; however, this flag is only cleared when the signal is fired due to focus loss and not when the Return/Enter key is pressed. This causes an unexpected double emission of the signal when focus is lost following a press of the Return/Enter key if the line edit's text was not further altered between the two actions. This change includes the Return/Enter press as a trigger for clearing the "edited" flag to make editingFinished()'s behavior more consistent and expected. Prevents slots in user code from triggering twice in situations where the line edit's current contents have already been handled, but still allows the end-user to force an emission of the signal via Return/Enter. The effect of the "edited" flag on the signals behavior has also been noted in the signal description as it was previously omitted. [ChangeLog][QtWidgets][QLineEdit][Behavior Change] Pressing the Return/Enter key in a QLineEdit will now also prevent editingFinished() from firing due to focus loss if the contents of the line edit have not changed since the last time the signal was emitted.
