This is an interesting insight, thanks.

There is an extra paren here.

Besides, SES is still broken. Try

emacs -Q etc/ses-example.ses

put the cursor on A13, for instance, then press the right cursor arrow
to move the cursor to B13 and press ENTER. The prompt starts editing the
contents of A13. Interestingly, if you cancel the minibuffer prompt with
C-g and press ENTER again, B13 is edited.

Apart from that, cursor movement is erratic: try to move the cursor to
the line after the last row of the spreadsheet, note how it is not
possible and it goes to one line below. Now press the up cursor arrow
and see how the cursor goes to the rightmost cell of the last row. This
problem may be unrelated to the bug you tried to fix. For all that I
know, it might be present before the change that caused this bug report,
I need to check.
