Reopening as a release blocker.

It appears that this new rule is far too eager, and matches a much wider range of inputs than intended. Here is a case where it changes an IndentationError into a SyntaxError:

$ cat bug.py
print()
    boom

On 3.9 (correct):

$ ./python.exe --version
Python 3.9.6+
$ ./python.exe bug.py
  File "/Users/brandtbucher/Desktop/GitHub/cpython/bug.py", line 2
    boom
IndentationError: unexpected indent

On 3.10 (incorrect):

$ ./python.exe --version
Python 3.10.0b4+
$ ./python.exe bug.py
  File "/Users/brandtbucher/Desktop/GitHub/cpython/bug.py", line 1
    print()
    ^^^^^^^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?

On 3.11 (incorrect):

$ ./python.exe --version
Python 3.11.0a0
$ ./python.exe bug.py
  File "/Users/brandtbucher/Desktop/GitHub/cpython/bug.py", line 1
    print()
    ^^^^^^^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?

I recommend that this either be fixed or reverted before the RC.
