#1 Refine class-method confusion heuristic

[Michael Welsh Duggan]

methods in the following form:

void NormApp::Notify(NormController::Event event,
class NormSessionMgr* sessionMgr,
class NormSession* session,
class NormServerNode* server,
class NormObject* object)
{

are thrown out as being a class which has been
mistakenly identified. The included patch fixes this
by making the check versus c++-class-name-before check
that it actually matches from the beginning of the
section (as opposed to the line).
