[O] [bug] As if there were no formulas

[Sebastien Vauban]

Hello,

Formulas are not shown anymore (with `C-u C-x =') as we introduce the use of
"symbolic" references (such as @>).

* Example

|   | Date of bill     | Amount |
|---+------------------+--------|
|   | [2011-10-04 Tue] |  69.02 |
|   | [2011-06-03 Fri] | 155.02 |
|   | [2011-02-01 Tue] | 180.01 |
|---+------------------+--------|
|   | Total            | 404.05 |
#+TBLFM: @>$3=vsum(@address@hidden);%.2f

* Problems

1. If I go on cell address@hidden' and do a `C-u C-x =', I don't see any 
formula --
   subject of this post.

2. Extra discovery: unless in "Visible mode", I don't see the `@' character in
   the TBLFM line. What I see is:

     #+TBLFM: >>$3=vsum(address@hidden);%.2f
              ^         ^
   Now that I think about it, it must be a side effect of:

   + hiding the markers
   + having `@' as extra marker for alert... Not such a judicious choice, then,
     for Org-Beamer... Using `!' could be a better choice?

Best regards,
  Seb
