pylint #4691 exit code should reflect the presence of errors or warnings [resolved]

pylint should only have an exit code of 0 if no errors or warnings were found.

I suggest the following exit status:

0: no errors or warnings 1: errors were found 2: no errors, but some warnings

0 can be found if only refactoring advices and coding conventions issues were found. A command line flag could be use to force R and C to be considered as warnings.
