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.
