Rename Method refactoring allows you to rename a nested method with a parameter name

[researcher175]

Rename Method refactoring allows you to rename a nested method with the parameter name of the outer method. It would be nice if Rope sent an alert to avoid missing annotations

Steps to reproduce the behavior:

1. Code before refactoring:

   
   def _calculate_tk(source):
   def c_int(x, nbits=32):
       return (x & ((1 << (nbits - 1)) - 1)) - (x & (1 << (nbits - 1)))
   
   def c_uint(x, nbits=32):
       return x & ((1 << nbits) - 1)
   
   tkk = [406398, 561666268 + 1526272306]
   b = tkk[0]
   
   d = source.encode('utf-8')
   
   def RL(a, b):
       for c in range(0, len(b) - 2, 3):
           d = b[c + 2]
           d = ord(d) - 87 if d >= 'a' else int(d)
           xa = c_uint(a)
           d = xa >> d if b[c + 1] == '+' else xa << d
           a = a + d & 4294967295 if b[c] == '+' else a ^ d
       return c_int(a)
   
   a = b
   
   for di in d:
       a = RL(a + di, "+-a^+6")
   
   a = RL(a, "+-3^+b+-f")
   a ^= tkk[1]
   a = a if a >= 0 else ((a & 2147483647) + 2147483648)
   a %= pow(10, 6)
   
   tk = '{0:d}.{1:d}'.format(a, a ^ b)
   return tk

2. Apply the Rename Method refactoring with the new name 'source' to the method 'c_int'
