providing context in the commit message

Writer: Deselecting the text with click after selecting whole document doesn't redraw.
Reproduce:
* Open Writer file.
* Put the cursor at the end of the file.
* Select all text.
* Click on the end of the file position or use -> arrow key.
* Selection is cleared after doing the prevous step, but the screen is not refreshed.

Fix:
* Redraw also after deselecting the selected text.
* Also move the redraw request for selections, into updateMarkers for better coverage.

this is a really well written change, the commit message is complete. it tells you about the problem, provides steps to reproduce the problem, then goes on to explain how the fix solves the problem. doesn't matter who is reading it, QA? yourself after a few years? this has it all. it doesn't depend on a ticketing system for further context.

another thing to note is that the commit message isn't a paragraph, but concise points. that makes it much more readable than if it were a text wall.
