bug#7284: [PATCH] `find-change-log' fails in *derived* Diff modes

Running `C-x 4 a' (add-change-log-entry-other-window) in a derived mode
of Diff mode (psvn-diff-mode, magit-diff-mode, and so on) does not open
the correct ChangeLog file.  The following patch fixes the problem.

Perhaps, more of the cases of Emacs's Lisp that have (eq major-mode ...)
should be converted to (derived-mode-p ...).  Obviously, they'll need
to be studied on a case-by-case basis since there might be cases when
only the exact major-mode is intended to be matched.

Thanks for Emacs,
