description:
lint: make the table containing the operator properties more readable
The C preprocessor does not require its arguments to be expressions, an
empty string is valid as well. This allows to replace the 0 in the
operator properties table with a space, making the 1 stick out.
Since the table is quite long, divide it into sections and add section
headers.
No change in the generated code.
