[O] org-table-edit-formulas misbehaving in 8.2.7b

[Luke Crook]

I just noticed that org does not jump to the correct cell in the table when 
examining formulas using "org-table-edit-formulas". 
This was working in 8.2.6.  In most cases, it will jump to a different 
location in the buffer.   Example table below.  
Note that I had to break the table formulae onto two 
lines to pass the 80 characters per line rule when posting.
