when working on objective-c files, the syntax highlighter easily break. this tends to happen after objective-c method calls.

check qcore_foundation.mm in qtbase:

method and variable names are yellow, while according to the color scheme they should not.

observation: it seems to be triggered by the `[[` sequence. if this sequence is broken up, e.g like:

    return [/* */ [/* */ [NSUUID alloc] initWithUUIDBytes:u] autorelease];

subsequent highlighting looks good (after closing/reopening the source file)
