problem parsing with statements

[15r10nk]

Some with statements can not be parsed by black.
They are unlikely to appear in real code, but they are valid python and can be parsed by cpython.

Examples

with (name_2 for name_0 in name_4):
    pass

with (a,*b):
    pass

None of these examples have a valid __enter__ or __exit__ and should fail at runtime.

black gives the following error:

error: cannot format example4.py: Cannot parse: 1:8: with a, *b:

Oh no! 💥 💔 💥
1 file failed to reformat.

Expected behavior

black should be able to parse and format this statements.

Environment

python -m black, 23.3.1.dev10+geb32729 (compiled: no)
Python (CPython) 3.11.3

Presumably related to #2926, and fixable by changing remove_with_parens() in linegen.py.
