Yay! Attached is a patch to both add-log and log-edit. Note that a few TODO's
are marked along add-log code where I couldn't understand what the code was
doing (just started to learn elisp... well, in fact just switched into emacs :)).

The major show-stoppers right now are:

* Couldn't get change-log-minor-mode to highlight the text as in
  change-log-mode.
* Would be nice to allow adding entries to the bottom of current change log
  block instead of the top.
* diff-add-change-log-entries-other-window has a somewhat strange behaviour and
  ends up showing two windows with the same Changelog/VC-log buffer (I think the
  bug was already there).

See that some changes were made into log-edit to seamlessly integrate with this
new feature in add-log.

As always, comments are welcome.

apa!
