The smart backspace handling required a preceeding
non empty text block. In this case, the fix introduces
a standard backspace (deletePreviousCharacter).

Depending on the XRender driver (probably), drawing a short straight
line can take quite a while when this line is transparent. On my
laptop's onboard ATI card, this meant that scrolling was unusably slow
when this transparent line was being drawn.
Fixed by avoiding the issue, since there is no actual need to use
transparency here. We can calculate the resulting color in advance
instead.
It was a bit confusing, since it reversed the order of the lines. When
this would be fixed, the added value of this action is very small, since
you can then also simply move your cursor one up before joining the
lines.
The dummy shortcut eater did not always work, we sometimes do have
mutual exclusive shortcuts in the same context.
The current solution is simpler: ignore text input when the control modifier
is used. This seems to be in line with other toolkits and applications.

Before, the selection was required to span multiple lines. Now, any
selection will trigger the line indenting functionality of
Tab/Shift+Tab. This should lead to less surprises.
Also, Shift+Tab will now always unindent the current line, even if there
is no selection, since there is nothing else sensible for this shortcut
to do.

the new approach makes it possible to use more edit features
inside the rename selection like cut/copy/paste. Furthermore
it compresses rename operations better on the undo stack.
When auto-indent is turned off, Qt Creator uses a simplistic approach of
copying the indentation string from the previous line. This was broken
when the cursor was positioned inside the indentation, since this caused
part of the indentation to go to the next line, which was then prepended
with the copied indentation, in effect increasing the indentation for
each new line.
The solution here was to copy the indentation from the previous block
only after inserting the new block, which causes the indentation of the
previous line to be cut off by exactly the right amount to keep the
indentation constant.

The extra area only updated the current *line* when the cursor moved, not
the entire paragraph. This left bold line numbers behind. The fix adds
the required update region when the cursor position changes blocks.
the fix makes the mouse cursor visible when the editor loses focus.
This fixes an issue with the completion box, where on mac and windows
no mouse cursor would be visible (it worked on X11 due to the way
X11 does mouse grabbing for popup windows).
This is necessary since a recent change in Qt 4.6 to how the
WaveUnderline is drawn. It makes sure the WaveUnderline repeats
correctly from one text item to another.
