[Tutor] Python, vim, indentation, and wrapped lines

[Poor Yorick]

I use Vim as my primary Python code editor.  I've always wondered if 
there is a way to make wrapped lines take on the indentation of the 
previous line.  Of course I mean *in the display only*, since I don't 
want any newlines introduced.  This would also be handy for me when 
editing indented html/xml documents.  Anyone know how to do this in vim?
