bug#5852: 23.1; Incorrect references in ses-mode |

I discovered this when emacs sometimes complains that I have circular
references in ses-mode files where there shouldn't be any. When
investigating the ses file I've noticed some cells contain references
that are incorrect. When I remove these incorrect references, the
complaints about circular references go away, so I strongly suspect
the problems are related. And even if I'm wrong, the incorrect
references is a bug.
While I haven't been able to create a simple test case where I get a
circular reference complaint, I can easily get to a state where there
are incorrect references. Create a ses file with these keystrokes:
C-x C-f s . s e s <return> <tab> 1 <return> C-o 2 <return>
<tab> <left> ( + SPC B 1 SPC A 2 <return>
C-n C-o 3 <return> ( + SPC B 2 SPC A 3 <return> C-a
C-o 4 <return> C-p C-SPC C-f M-w C-n C-b C-y C-n C-y
C-x C-s
In the resulting file, cell B2 has cell B4 incorrectly listed among
its references:
(ses-cell B2 3 (+ B1 A2) nil (B3 B4))
Only B3 does actually reference B2.
