IDLE inserts an extra blank line after the prompt after encountering a SyntaxError:

```
>>> 1 + 2
3
>>> print('Hello')
Hello
                                     v-- Missing single quote!
>>> d = {1: 'uno', 2: 'dos', 3: 'tres}
	 
SyntaxError: EOL while scanning string literal
>>> print('Hello')
	 <-- Extra blank line and whitespace (tab and space).
Hello
>>> 1 + 2
	 <-- Extra blank line and whitespace (tab and space).
3
>>> 
```

Notice the line starting with ">>> d =" above contains a missing single quote which causes a "SyntaxError: EOL while scanning string literal". This causes IDLE to insert extra blank lines with one tab and one space after every input.

The old behavior looked like:

```
>>> 1 + 2
3
>>> print('Hello')
Hello
>>> d = {1: 'uno', 2: 'dos', 3: 'tres}
     
SyntaxError: EOL while scanning string literal
>>> print('Hello')
Hello
>>> 1 + 2
3
```
