When I enter Python help in the REPL, if I type "exit", I get:

```
Help on Quitter in module _sitebuiltins object:

exit = class Quitter(builtins.object)
 |  exit(name, eof)
 |
 |  Methods defined here:
(...)
```

If I try exit(), I get an error:

```
help> exit()
No Python documentation found for 'exit()'.
Use help() to get the interactive help utility.
Use help(str) for help on the str class.
```

It propose supporting to just type "exit", similar to "quit", to quit the help.
