Patch from Joey Adams:

(15:27:11) joeyadams: ccanlint's handle_no_tests apparently has a bug.  It makes the test directory with 
0600 permissions, so it can't be used.  the x bit provides directory listing privilege
(15:27:25) joeyadams: this gives me Permission denied when I try to run it
(15:28:34) joeyadams: Changing the opcode to 0700 makes the creation of run.c work
