I was just looking at this post which describes how to wrap entire words in vim. The accepted solution was this:

:set formatoptions=l
:set lbr

Which takes this text (tabs are shown as \t):

 *Inside of window                        *Outside of window
|---------------------------------------|    
|\t\tthis is a like of text that will wr|ap here                            
|\t\tcan you see the wrap               |
|                                       |
|---------------------------------------|

This accomplishes a behavior like this (tabs are shown as \t):

 *Inside of window                        *Outside of window
|---------------------------------------|    
|\t\tthis is a like of text that will   |
|wrap here                              |
|\t\tcan you see the wrap               |
|                                       |
|---------------------------------------|

I would however like to redefine this function. I would like the wrapped line to have the same number of tabs in front of it that the line above has plus one. Ie:

 *Inside of window                        *Outside of window
|---------------------------------------|    
|\t\tthis is a like of text that will   |
|\t\t\twrap here                        |
|\t\tcan you see the wrap               |
|                                       |
|---------------------------------------|

Any ideas?
