Excellent idea! =)

I'd suggest advising the function that brings up the *VC-log* buffer
so that it does something useful like storing the current directory
directory in a variable before opening the log.

Ah, here's how it can work:

- Whenever you call log-edit, notice the filename and store it in some
  variable. This will probably be a list.

- After you commit, iterate over the list, getting vc-workfile-version
  for each file and coming up with the links you want to use in your
  planner note.

You may be able to get it to produce a note like this:

.#2 Commit planner-config.el 1.2, emacs-wiki-config.el 1.5

       * annotation
       * annotation
       * annotation       

where the source text is

.#2 Commit 
[[/Users/jklymak/emacs-common/planner/planner-config.el][planner-config.el]] 
1.2, [[/Users/jklymak/emacs-common/planner/][emacs-wiki-config.el]] 1.5

       * annotation
       * annotation
       * annotation

Feel free to steal ideas from remember-planner.el. There's a
remember-planner-add-xref there.

I'll add planner-copy-note to my TODO, but probably won't be able to work on
it this weekend.

(defun planner-copy-note (page &optional xref)
 "Copy the current note to PAGE.
Link both notes to each other. If XREF is non-nil, replace the original
note body with a link to the note on PAGE."
 (interactive (list (planner-read-non-date-page (planner-file-alist))
                    current-prefix))
 ;; Some magic goes here.
 ;; planner-narrow-to-note might be useful.
 ;; planner-update-note from planner-experimental
)

Come to think of it, perhaps planner-update-note should just be extended so that
it creates the note if necessary, and allows the transformation of the current
note into a cross-reference if you feel like it.
