Hey Phil,

Here is an example. You can switch lexers in lines 37/38. Line 37 has 
the white margin.
I'm on Windows 7 64-bit using snapshot 'eb936ad1f826' with Python3.4 
64-bit and PyQt4.11.3.

Oh, I just realized I should mention that I'm only compiling QScintilla, 
not the entire PyQt4!
Compiled the source and just overwrote the 'qscintilla2.dll' in 
'Python34\Lib\site-packages\PyQt4'.

Cheers,
Matic
