Hi, Bastien.  Thanks for looking into this.  Let me start by saying that I'm
completely satisfied with the mechanism of joining formulas with the "::"
notation, and especially with the convenient editing of such formulas with
"C-c '".

But if the multiple TBLFM lines work as I think you're describing, then I
still have some gap in my understanding.

Here's my simple test table, with multiple formulas, joined by "::":

    #+TBLNAME: test1
    | 1 | 2 |   |
    | 4 | 5 |   |
    | 7 | 8 | 9 |
    #+TBLFM: @1$3='(+ 10 7)::@2$3='(+ 11 9)::@3$1=42

If I hit C-c C-c while the point is on the one and only TBLFM line, I get:

    #+TBLNAME: test1
    |  1 | 2 | 17 |
    |  4 | 5 | 20 |
    | 42 | 8 |  9 
    
I.e.,exactly the intended result.

Here is the same table, but with the formulas spread across three different
lines:

    #+TBLNAME: test2
    | 1 | 2 |   |
    | 4 | 5 |   |
    | 7 | 8 | 9 |
    #+TBLFM: @1$3='(+ 10 7)
    #+TBLFM: @2$3='(+ 11 9)
    #+TBLFM: @3$1=42

If I hit C-c C-c while the point is on the FIRST TBLFM line, I get:

    #+TBLNAME: test2
    | 1 | 2 | 17 |
    | 4 | 5 |    |
    | 7 | 8 |  9 |

This is what I expected.  If I now proceed to hit C-c C-c while the point is
on the SECOND TBLFM line, I get:


    #+TBLNAME: test2
    | 1 | 2 | 17 |
    | 4 | 5 |    |
    | 7 | 8 |  9 |
    
I.e., there is no change whatsoever.  If I then hit C-c C-c while the point is
on the THIRD TBLFM line, I get:

    #+TBLNAME: test2
    | 1 | 2 | 17 |
    | 4 | 5 |    |
    | 7 | 8 |  9 |
    
I.e., again there is no change whatsoever.

I might add that if I do carry out these operations with table debugging
turned on (C-c {), I do NOT get prompted by the debugger when trying to
process the second and third TBLFM lines.

As I said above, I'm happy with the "::" solution and am happy to let this
topic drop, but I'm eager to expand my Org-mode skills.  Please let me know
what I'm missing.

Thanks again.
