[QScintilla] QScintilla folding display issue with Qt4 (did not exist with Qt3)

[Gilles Depeyrot]

Thanks for the hint which effectively corrected the problem (which 
appears on rhel5).

With the proposed change in Editor.cpp, the margin color is red. We 
changed that using the QScintilla function "setFoldMarginColors".
What is the interest of the first argument to "setFoldMarginColors" ? It 
doesn't seem to have any visible impact.

Has this change to Editor.cpp been proposed for inclusion in the 
Scintilla sources?

Best regards,
Gilles
