[CWEB] Improce productions 33, 118, and 153.
Rule 33: Comma-separated lists of variables like 'int x,y,z;' had a
full blank space (see, e.g., the SGB book), in stark contrast to the
resuts of rules 4 and 14.
Rule 118: Multiple type definitions were separated by _two_ spaces,
because the type after the comma brings its own space from rule 117.
This might look better with 'app(opt); app('9');' after the comma.
Rule 153: Long lines with multiple typename declarations now have the
chance to be broken after the comma.
