Bug report

Bug description:

Infilecmp.cmpfiles, when the path is not stat-able, it will be put in the "fancy" files. This should include paths that would raiseValueError.

Note thatfilecmp.cmp shouldnot be protected against that since it already ignores an OSError possibly raised byos.stat.

Similarly,filecmp.dircmp should not suppressOSError orValueError when listing the directory contents. It should however silenceValueError when checking the common files since it already silence anOSError.

TL;DR: Only protect againstValueError if the current code is already protecting againstOSError.
