In auto-fill-mode, I want emacs to auto-fill paragraph with hanging indentation, like this:

```
This is an example of hanging indented
    paragraph. The first line is indented
    less than the following lines in a
    paragraph.

Another paragraph starts from here, and
    lines are broken.

```

How to do this?

You can achieve the effect you want automatically by putting the following lines into you .emacs file:

```lisp
(setq adaptive-fill-function '(lambda () "    "))

```

The string at the end of the line is the width of the hanging indent.
Simply indent the second line manually. Then when you hit `M-q` the whole paragraph will be indented the way you want.
