To Artifact [52c46d5774]:

• File tests/io.test — part of check-in [50a34ec0ff] at 2017-04-14 09:05:01 on branch core-8-6-branch — Don't use "0%o" format in test-cases, as it suggest's it's the normal way to format octal numbers: it isn't. Better use "%#o". Add tests for "format" and "scan" corner-cases which weren't documented (except in TIP's) neither had tests before. (user: jan.nijtmans size: 260691)
