changelog and diff-add-change-log-entries-other-window (git, HG)

[Uwe Brauer]

Hi 

add-change-log-entry-other-window works great in lisp files, and with
some tweaks in LaTeX files, but in other files I am missing some context
information.

So I thought, for files that are under git or HG, to run vc-diff
and then 
diff-add-change-log-entries-other-window

But when I do that, nothing of the diff files is inserted, I cannot see
any difference to add-change-log-entry-other-window.

What do I miss here.

I searched emacs wiki for any enhancement of 
add-change-log-entry-other-window
in the sense that it would add more context based information but cannot
find anything.

Any comments?

Regards
