I want to indent all lines of a multi-line string except the first, without wrapping the text. 

For example, I want to turn:

```
A very very very very very very very very very very very very very very very very
long mutiline
string

```

into:

```
A very very very very very very very very very very very very very very very very
     long multiline
     string

```

I have tried

```
textwrap.fill(string, width=999999999999, subsequent_indent='   ',)

```

But this still puts all of the text on one line. Thoughts?
