Right now if you have a selection, and you enter a bracket/quote,
surrounds it with quotation marks, and selects the entire quote. This
change should change the behaviour to selecting the interior of the
quote instead.

The motivating example for me was autocomplete, where after
autocompleting a function the arguments are selected, so if you want
to insert a string literal right now you have to delete the selection
before you can enter the quotes. With the proposed fix, it'll be
rather more fluid.
