Issue 104065

1: Read LnkX.ods: xx=B1=3,  and zz=B2=4*B1=12;
2: Read LnkY.ods: aa=C2='file:///C:/Docu.../LnkX.ods'#$Sheet1.B1; result: 3. OK.
3: insert a row before row 1 in LnkX.ods; now, B1 is blank, and B2=3. Save file.
4: close and reopen LnkY.ods; OO asks: 'update links?'. Click yes. Now, aa=0
because, in LnkX.ods,  B1=0, because the reference (in aa=) to cell B1 has not
been updated to point to B2. OK; it would be difficult for a formula in LnkY to
keep track of changes in another file like LnkX. (In LnkX, zz is still 12
because Calc was smart enough, in the same SS, to change the formula from
'=4*B1'  to  '=4*B2'.)
 A solution to the above problem would be to assign a variable name such as 'Xa'
to cell B1 in LnkX, and to use that name in the aa formula, instead of the cell
name B1. Possible formula: aa='file:///C:/Docu.../LnkX.ods'#Xa; Then, Calc would
keep track of Xa (eg, when a row in inserted before), and the aa formula would
still give the right result.
