[issue44317] Problems of int literal SyntaxErrors

[wyz23x2]

Another 2 problems:
1.
>>> 0b1112
  File "<stdin>", line 1
    0b1112
         ^
SyntaxError: invalid digit '2' in binary literal
>>> 0o5780
  File "<stdin>", line 1
    0o5780
        ^
SyntaxError: invalid digit '8' in octal literal
But:
>>> 0x2fag
  File "<stdin>", line 1
    0x2fag
    ^^^^^^
SyntaxError: invalid syntax. Perhaps you forgot a comma?
>>> 
Is this expected?

2.
>>> 0o91
  File "<stdin>", line 1
    0o91
     ^
SyntaxError: invalid digit '9' in octal literal
>>> 0b21
  File "<stdin>", line 1
    0b21
     ^
SyntaxError: invalid digit '2' in binary literal

The ^ is misplaced again, even though, say the 0b1112 example above works.
