check-code: improve test-check-code error diffs Whenever check-code finds something wrong, the diffs it generated were fairly hard to read. The problem is that check-code before this change would list files that were white listed using no- check- code but without a glob marker. Whereas, the test-check-code.t expected output has no-che?k-code (glob) in order to avoid having itself flagged as a file to skip. Thus, in addition to any lines relating to things you did wrong, all of the white-listed files are listed as changed. There is no reason for things to be this painful. This change makes the output from check-code.py match the expected output in test-check-code.t
