Capture feature suggestion: place the mark from a template

["Colin Fraizer" <orgmode@cfraizer.com>]

I use a capture template like this:

("t" "Todo" entry (file+headline "todo.org" "Tasks") 
  "* TODO %?\n  :HIDDEN:\n  %U\n  :END:\n%!" :prepend t)

to create todo items.  I want the cursor to be at the end of the
headline so I can type that in, but then I want to be able to quickly
jump to the end so I can type any details that I want.

I use "the mark" for that purpose, so I can type "C-x C-x" to jump
right where I want.  So I modified the function
org-capture-place-entry to add the following lines:

    (goto-char beg)
    (if (re-search-forward "%!" end t)
        (progn
          (push-mark nil t nil)
          (replace-match "")))

just before the final (goto-char beg) that will put the cursor
position at "%?".

(I guess I could have put that following ``(goto-char beg)'' inside
that ``(progn ...)''.)

Would anyone else find this a useful addition to the capture template
mechanism?
