[O] Demoting in plain list displays asterisk as space

[Rainer Stengele]

Hi all,

Having this item list:

- 1
- 2

with cursor in the "-2" row demoteing the item with org-shiftmetaright results 
in

- 1
    2

where the expected "  * 2" is displayed as "    2".
describe-char with cursor at the expected asterisk position reveals that "*" is 
displayed as space:

-------------------------------------------------------------------------
            position: 7 of 10 (60%), column: 2
            character: * (displayed as *) (codepoint 42, #o52, #x2a)
    preferred charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x2A
               script: latin
               syntax: _        which means: symbol
             category: .:Base, a:ASCII, l:Latin, r:Roman
             to input: type "C-x 8 RET 2a" or "C-x 8 RET ASTERISK"
          buffer code: #x2A
            file code: #x2A (encoded by coding system utf-8-dos)
              display: composed to form "*" (see below)

Composed by the rule:
        (? )
The component character(s) are displayed by these fonts (glyph codes):
  : uniscribe:-outline-DejaVu Sans 
Mono-normal-normal-normal-mono-12-*-*-*-c-*-iso8859-1 (#x03)
See the variable ‘reference-point-alist’ for the meaning of the rule.

Character code properties: customize what to show
  name: ASTERISK
  general-category: Po (Punctuation, Other)
  decomposition: (42) ('*')

There are text properties here:
  composition          [Show]
  fontified            t
  keymap               [Show]
  line-prefix          ""
  mouse-face           highlight
  wrap-prefix          [Show]
-------------------------------------------------------------------------

Demoting once more results in:
- 1

    +

I cannot seem to find the reason why the "*" is displayed as empty char (space).
I already found out that there are no overlays at that point.
Does anybody have a hint?

Thank you.
