fdo#43090: Improve auto close brackets

Now it works this way:
* Auto close in end of current line of formula
* Auto close when we have "<?>" selected
* Auto close when we're in the beginning of current line.

We're adding a space between the brakets, like this: "[  ]" and putting the
cursor in the center of these brackets.
