[issue10289] Document magic methods called by built-in functions

[Andy Maier]

Andy Maier added the comment:

I reviewed the description of the built-in functions in Python 2.7, and found these issues:

1. The following built-in functions do not mention their underyling __special__ functions:
- cmp()
- delattr(), getattr(), hasattr(), setattr()
- complex(), int(), long(), float()
- hash()
- len()
- str()
- int(), oct()

2. The following built-in functions list the __special__ functions they invoke as text that is not a hyperlink:
- dir()
- format()
- hex()

3. The following built-in functions could be improved from the description of the 3.x version:
- bool(): References and links from 3.x version could be added.
- bytearray(): References from last line of 3.x version could be added.
- callable(): Wording "if they have a..." could be improved by using 3.x wording.

4. The codepage of the ASCII string for chr() is not documented.

Andy
