Tracking changes

[Joakim Hove]

Hello,

I wondered if there was a mode in emacs which allowed the tracking of
changes, i.e. consider the following text:

   "Bob has a red car"

Now, it turns out that Bob has bought a new car, which is blue, and
the text must be updated accordingly. What I would like was some mode
which retained (a marked up/highlighted version of) the old text, "red"
in this case, and also highlighted/marked up the new version to
indicate that it was new:

   "Bob has a _red_ *blue* car"

I know of the ediff-compare-** commands, which are very good, but for
now I would like the possibility to keep everything in one document.

Any suggestions?
