[QScintilla] Tab-Width

[Nicholas Sloan]

Alright, I'll probably be posting more often now, since I'm at a point 
in my project where a lot of my focus is going to be on the editor 
component.

I am calling QsciScintilla::setTabWidth(2); in the constructor of a 
class that inherits QsciScintilla. I have used QsciScintilla::setFont(); 
to set a monotype font. setTabWidth() is changing the tab-width, as 
expected, however, a value of 2 yields the width of approximately 1 
character. A value of 3 yields 1 and 1/2 characters, and a value of four 
actually yields the desired 2 characters. It appears that 1 "character" 
as set by setTabWidth() is about half the width of an actual character.

Is this behavior desired or expected for some reason? I can't seem to 
find any rationale for it.
