The syntaxic coloration of preprocessor macro don't work correctly

The color of the code inside a #if can be wrong if there is an indentation of the marco.

For example, copy the following code in Qt Creator:

#define TRY 0
#define TRY2 1

function_1(....);
function_2(....);
function_3(....);
function_4(....);
function_5(....);

#if TRY == 0
function_1(....);
function_2(....);
#if TRY2 == 0
// Text
QDrag *test;
function_1();
#endif
function_3(....);
function_4(....);
function_5(....);
#endif
