Better documentation of parser error messages (line and column numbers)
Currently, we have error messages like this:
ERROR: final.mod:201.1-3: syntax error, unexpected NAME
The reason usually is that a semicolon is missing in the previous line, but people only look in the current line. If the error starts at 1, we might want to change the error message to
ERROR: final.mod:201.1-3: syntax error, unexpected NAME. Please also check whether the previous line was terminated correctly with a semicolon.
