Preemptive double quote insertion does not discard closing quote.

[vext01]

When you have parentheses assist turned on, insertion of an open bracket will insert a close barcket. If you then insert a close bracket, no further text is added, as it is assumed the close bracket was already inserted.

Compare this to the double quote behavior. If you type two double quotes, you end up with """".

I would add to this issue that in certain dialog boxes, namely for Plot 2D and Plot 3D, the behavior for close brackets results in the same problem as with the quotes in the normal input, as described above.

Following the fix, I would suggest that the same highlighting to match parenthesis should be used for quotes, for consistency.

Issue resolved in #231 is no longer fixed since the recent change to BTextCtrl in 8d9a5e1
