Moveconfig already attempts to remove empty #if/#endif blocks when there is a matching CONFIG_ being moved. Add a second pass which covers files without a match.

• pattern = r'^\s*#\s*if.*$\n^\s*#\s*endif.*$\n*'

• with open(header_path) as f:

•    data = f.read()
  

• new_data = re.sub(pattern, '\n', data, flags=re.M)
