Title: Re-issues 5893

**But** rewrite_input is completely undocumented:
- %autocall is the only thing I know of that rewrite input,
- notebook receive a `raw_input` field which is `undefined`.
- And the `transformed_input` one has :
1. the color escape code
2. a fancy leading `->` that you absolutely don't want to set as cell's text.

eg:
```
%autocall
print 'a'
```
send to the notebook
```
transformed_input: "[0;34m-> [0mprint('a')",
raw_input: undefined
```

Me sad, and don't know what to do ... :-( @fperez ?
