summary:
   Issue #14769: test_capi now has SkipitemTest, which cleverly checks
for "parity" between PyArg_ParseTuple() and the Python/getargs.c static
function skipitem() for all possible "format units".

You sensibly only test printable ascii chars, which are in the contiguous range 32 to 127 inclusive. So it makes no sense to claim otherwise and then deny the wrong claim, or to enlarge the range and then shrink it again.

+        This function brute-force tests all** ASCII characters (1 to 127
+        inclusive) as format units, checking to see that

With a few exceptions**, test all printable ASCII characters (32 to 127 inclusive) as...

+
+          ** Okay, it actually skips some ASCII characters.  Some characters

** Some characters ...
+             have special funny semantics, and it would be difficult to
+             accomodate them here.

+        for i in range(1, 128):

for i in range(32, 128):


+            if (not c.isprintable()) or (c in '()e|$'):

if c in '()e|$':
