Parameter range is incorrect for *args and **kwargs #10282
Description
I'm working on a fix for the flake8-unused-arguments (ARG) rules that would delete them.
While working on this, I noticed that the *args and **kwargs Parameter.range does not include the *.
I think that Parameter.range should include * or **, leaving Parameter.name.range for the actual name range if needed.
def f(*args, **kwargs): pass
# ~~~~ ~~~~~~ <-- actual range
# ^^^^^ ^^^^^^^^ <-- expected rangeSee the currently generated AST
Here I would expect the Parameter range to be 1 longer than the Identifier range.
And here I would expect the Parameter range to be 2 longer than the Identifier range.
If this is indeed considered a bug, I have a PR ready to fix it.
