[Message part 1 (text/plain, inline)]

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':


I've found a case where org-mode fails to honor vertical list spacing
as it has in the past.  I've attached "example.org" for illustration.

Here are steps to reproduce the behavior I'm seeing:

(1) emacs -Q example.org

    After doing this, the major mode should be "Org", and the
    minibuffer should contain the text "OVERVIEW"

(2) Press SHIFT-TAB a few times, until the minibuffer contains the
    text "SHOW ALL".  At this point, example.org is fully expanded.

(3) Position point immediately after the word "bar1", on line 5.

(4) Press M-RET.  Org inserts a "-" on line 6.  The expected behavior
    (from prior versions) is that the "-" should be placed on line 7.

    In other words, pressing M-RET should leave a blank line when a
    list contains blank lines between items.  In emacs 24.0.93, org
    does not leave a blank line.

example-24.0.93.org contains the results of performing these steps
with emacs-24.0.93.

For contrast, example-24.0.92.org contains the results of performing
these steps with emacs-24.0.92.  example-24.0.92.org illustrates the
behavior I'm expecting to see.  Essentially, it's the positioning of
the new list element after "bar1".

I can share one additional observation.  In emacs-24.0.92

    C-h v org-blank-before-new-entry

contains the value 

   ((heading . auto)
    (plain-list-item . auto))

In emacs-24.0.93, "C-h v org-blank-before-new-entry" states:

   org-blank-before-new-entry is a variable defined in `org.el'.
   Its value is nil
   Original value was 
   ((heading . auto)
    (plain-list-item . auto))

Perhaps the value of org-blank-before-new-entry is getting clobbered?

For a start, this:

org-footnote.el:(defvar org-blank-before-new-entry nil) ; silence byte-compiler

is bogus (the relevant syntax is (defvar foo)).

Probably so are these:

org-footnote.el:(defvar org-export-footnotes-seen nil) ; silence byte-compiler
org-footnote.el:(defvar org-export-footnotes-data nil) ; silence byte-compiler

Glenn,

I believe you found it.

Applying the change in org-footnote.el.patch (attached) corrects the
vertical spacing issue I noticed.

I removed the bogus values.

Bastien, could you merge the fix to Org upstream?  Thanks.
