How to highlight lines changed since the last save of a file in Vim?

Is it possible to have Vim highlight the changed lines since the last save? I know it can be done with version control, but can it be done without? I do not want to use any version control system, because the code I work on does not have that.

I think, UltraEdit has something like that.

Straight from Vim documentation (see :help :DiffOrig):

if !exists(":DiffOrig")
    command DiffOrig vert new | set bt=nofile | r # | 0d_ | diffthis
          \ | wincmd p | diffthis
endif

Then just do :DiffOrig et voila!

From Vim Wiki:

Type :changes to display lines where changes occurred.

Use g; and g, to jump to changed lines.

You need a temporary file to compare against, and I'm not sure that Vim has one (it has a .swp file but I don't know how it could be exploited).

Anyway a (quirky) possibility could be to use the generic SCMdiff and write a commandline script that performs a diff between the current file and a .tmp version of it. You should also map a command that saves the .tmp file for the current version, maybe calling automatically each time you save.

if you're using CVS, Git or Subversion for your source files then this plugin script will do what you want: VIM svndiff

it probably wouldn't be too difficult to get it to work from a diff of a temp file instead (if it doesn't have that option already).
