Peter Eisentraut <peter at eisentraut dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |peter at eisentraut dot org --- Comment #3 from Peter Eisentraut <peter at eisentraut dot org> --- My general impression is that level =2 looks for substring matches, like /* fall through because this code is weird */ whereas level =3 only looks for some exact strings, like /* FALLTHROUGH */ This could be made clearer in the documentation.
