| skipitem() in the same file. (If so, shame on you!) | |
| With a few exceptions**, this function brute-force tests all | |
| printable ASCII*** characters (32 to 126 inclusive) as format units, | |
| checking to see that PyArg_ParseTupleAndKeywords() return consistent | |
| errors both when the unit is attempted to be used and when it is | |
| skipped. If the format unit doesn't exist, we'll get one of two | |
| specific error messages (one for used, one for skipped); if it does | |
| exist we *won't* get that error--we'll get either no error or some | |
| other error. If we get the specific "does not exist" error for one | |
| test and not for the other, there's a mismatch, and the test fails. | |
| ** Some format units have special funny semantics and it would | |
| be difficult to accommodate them here. Since these are all | |
| well-established and properly skipped in skipitem() we can | |
| get away with not testing them--this test is really intended | |
