wraps loses keywords

[brl0]

Thanks for the great project!

The decorator boltons.funcutils.wraps seems to lose keywords passed to the wrapped function. This does not happen with functools.wraps.
Here is a silly example:

from boltons.funcutils import wraps

def flip(f):
    @wraps(f)
    def wrapper(*args, **kwargs):
        return f(*reversed(args), **kwargs)
    return wrapper

def pow(x, y, msg=""):
    """Print msg and raise x to the power of y."""
    print(f"{x=}, {y=}")
    if msg:
        print(f"{msg=}")
    result = x ** y
    print(f"{result=}")
    return result

flipped_pow = flip(pow)
flipped_pow(3, 2, msg="abc")

---

Expected:

x=2, y=3
msg='abc'
result=8

---

Actual:

x='abc', y=2
msg=3

TypeError

     17 flipped_pow = flip(pow)

     13 if msg:
     14     print(f"{msg=}")

I also noticed that if I make msg keyword only, as below, it works:

def pow(x, y, *, msg=""):
