ADDxxx param statements were too greedy on the mofidiers and were
matching more than it should in cases where there are no newlines after
the statement like:
'%ADD12C,0.305*%%LPD*%', in a single line. The '%' was not exluded form
modifiers so it got confused with the %LPD*% concatened.
top_copper.GTL example was changed to be in a single line now with no
spaces at all and it works well.
