I like to leave a blank line at the end of items that have bodies, but I
found functions like org-metaup, org-metadown, and org-refile were
leaving that blank line behind. Here's a patch to fix that:
--8<---------------cut here---------------start------------->8---
diff --git a/lisp/org.el b/lisp/org.el
index 5eb0bc8..e3d71b7 100644

I can't think of a reason you would want to leave trailing blank lines
behind, but in case some people rely on that behavior, here's an
alternate patch that creates an option called
org-preserve-trailing-blank-lines:

If this is accepted, perhaps the function org-back-over-empty-lines
should be renamed to org-back-over-lines.

These commands treat empty lines as belonging to the entry
below the empty line - which is, I think, the right convention here.

I now understand this is a formatting convention issue. Here is an
updated patch that looks at the setting for `heading' in the variable
org-blank-before-new-entry:
diff --git a/lisp/org.el b/lisp/org.el

I'm trying to figure out when this patch is useful. I understand this
is when `org-blank-before-new-entry' doesn't set heading to t or auto,
but I don't understand what it the difference the patch introduces then.
Could you send a _visual_ example, with useless empty lines that you
want to get rid off when org-metaup etc ?
Thanks!

Convention 1: Newline above headings
This seems to be used more often when the body does not have delimiting
newlines.
Configuration:
--8<---------------cut here---------------start------------->8---
(setq org-blank-before-new-entry '((heading . t)
(plain-list-item . t)))
--8<---------------cut here---------------end--------------->8---
Org example:
--8<---------------cut here---------------start------------->8---
* Section
** Subsection 1
Body
** Subsection 2
Body
--8<---------------cut here---------------end--------------->8---
Convention 2: Newline after bodies
This seems to be used more often when the body does have delimiting
newlines.
Configuration:
--8<---------------cut here---------------start------------->8---
(setq org-blank-before-new-entry '((heading . nil)
(plain-list-item . nil)))
--8<---------------cut here---------------end--------------->8---
Org example:
--8<---------------cut here---------------start------------->8---
* Section
** Subsection 1
Body
** Subsection 2
Body
--8<---------------cut here---------------end--------------->8---
I've seen both conventions in use on Worg and in Org-mode tutorials.
I just tested these configurations and Org examples out with the patch
and it seems to work well. I've been using the patch on my systems for
a while now and haven't noticed any bad side-effects.
Let me know if you need any other information.
Regards,
Jason

I'm back to this patch -- thanks for the clear explanations.
However, with your patch, I get a weird behavior.
Config:
,----
| (setq org-blank-before-new-entry '((heading . nil)
| (plain-list-item . nil)))
`----
Test file:
,----
| * Section
|
| ** Subsection 1
| Body
|
| ** Subsection 2
| Body
`----
Trying to move Subsection 1 down (with org-metadown):
,----
| * Section
| Body <<<<<< ??
|
| ** Subsection 2
|
| ** Subsection 1
| Body
`----
Are you able to reproduce this?

I finally had a chance to test this out with the latest Org from git and
a vanilla Emacs config, and I was unable to reproduce the behavior you
saw. Here is what I did:
$ git clone git://orgmode.org/org-mode.git
$ emacs23 -Q &
(Edit org.el to re-introduce patch.)
$ cd org-mode/
$ git diff
diff --git a/lisp/org.el b/lisp/org.el

--- a/lisp/org.el

Then I evaluated the following in Emacs:
(delete "/usr/share/emacs/23.2/lisp/org/" load-path)
(add-to-list 'load-path "~/tmp/org-mode/lisp")
(require 'org-install)
(setq org-blank-before-new-entry '((heading . nil)

You can see what happened on my screen with the following:
wget http://98.129.169.48/tmp/emacs-testing.time
wget http://98.129.169.48/tmp/emacs-testing.script
scriptreplay emacs-testing.time emacs-testing.script
Would you mind testing it out again?

Jason
