* text.C:

* text.C:
  - LyXText::breakParagraph(): Redo paragraphs before setCursor()
  - LyXText::insertChar(): ditto

* lyxfunc.C: take into account BufferView::update() returned value for WorkArea redrawing.

* BufferView::update(): we also need a second step in singlePar mode.

* WorkArea.C
  - startBlinkingCursor(): also show the cursor
  - stopBlinkingCursor(): also remove the visible cursor
  - processKeySym(): stop and start the cursor blinking instead of merely hide and show it.
