[Orgmode] Found my problem with date-stamping

[Robert Goldman]

I use C-u C-c C-t followed by "d" when I mark my tasks as DONE so that
they move to the done state instead of waiting, which is the next state
in the progression.

Unfortunately, that prefix argument is, as far as I can tell, bound over
the entire process of marking the task as done.  This means that when we
get to org-store-log-note, we bump into the following line:

    (when (or current-prefix-arg org-note-abort)
      (setq lines nil))

Which means that org carefully composes the note with the datestamp...
and then throws it away.  Unfortunately, I don't really know what the
test for current-prefix-arg is here for, so I don't feel comfortable
just removing it.  Can anyone offer enlightenment (this might be a good
place for an explanatory comment...)?

Thanks,
R
