Okay, more seriously, here's a Vim script...

The first two lines are the configuration, you shouldn't have to change
anything below them.

:set tabstop=8 shiftwidth=8
:set expandtab

:g/^/call MaybeRetab()
func! MaybeRetab()
  normal! ^
  let before = virtcol('.')
  .retab
  let after = virtcol('.')
  if before != after
    undo
  endif
endfunction
