"Soft" indent with visual-line-mode?

[Tim Stewart]

Hello Emacs Help,

I like the idea of using longlines-mode or visual-line-mode to spend  
less time formatting code as I write.  However, it is not useful to me  
when the wrapped lines start in the first column and break up the flow  
of the code.

As an example, this is what I get now with a line that is indented 4  
spaces.  This is all one line, wrapped by the editor for me:

    This is a test of the emergency broadcast system.  This is only a  
test.  In
the event of a real emergency, your head would have exploded.

And this is what I want:

    This is a test of the emergency broadcast system.  This is only a  
test.  In
    the event of a real emergency, your head would have exploded.

I've heard this referred to as a "soft" indent.  I believe that Visual  
SlickEdit 9 and Kate both support this feature if you'd like other  
examples.

Does anyone know of a feature or add-on for Emacs that can accomplish  
this?  I've scoured the 'Tubes and can't find anything.

Thanks for the help,
