Initial commit of pragma newsource pragma newsource enables a source code variant as follows: 1. no line numbers 2. no implied comments at the end of lines 3. all comments must be introduced by a comment character 4. spaces are allowed in operands (4) is not quite complete. This commit handles "operandless" instructions (anything where the parser calls skip_operand()) and expression parsing.
