Serge Guelton 5ef88bdb68 Fix isInSystemMacro to handle pasted macros
Token pasted by the preprocessor (through ##) have a Spelling pointing to scratch buffer.
As a result they are not recognized at system macro, even though the pasting happened in
a system macro. Fix that by looking into the parent macro if the original lookup finds a
scratch buffer.
