The callback passed to UpdateDiff() is superfluous: in the synchronous case screen.Redraw() is not needed anyway (since the screen is redrawn at every iteration of the main loop), and in the asynchronous case UpdateDiff() can just call screen.Redraw() directly.
When updateDiffSync() is called asynchronously, it should lock the line array when calling Bytes(), to prevent race if the line array is being modified by the main goroutine in the meantime.

UpdateDiff()interface: remove unneeded callback (sinceUpdateDiff()can simply callscreen.Redraw()directly in the async case, and doesn't need to call it at all in the sync case).LineArrayinstead of single lines #3224).
