Error codes checkup and rustdoc test fix

This PR does a few things:

 * fix how rustdoc checks that an error code has been thrown (it only checked for "E0XXX" so if it appeared in the output because the file has it in its name or wherever, it passed the test, which was incorrect)
 * fix the failing code examples that weren't throwing the expected error code
