        <pre>Description:
Undo of deleting a row exceptional slow compared to (insert/delete/ or reject
delete row)

Steps to Reproduce:
1. Open <span class=""><a href="http://bugs.documentfoundation.org/attachment.cgi?id=161647" name="attach_161647" title="Example file">attachment 161647</a> <a href="http://bugs.documentfoundation.org/attachment.cgi?id=161647&action=edit" title="Example file">[details]</a></span>
2. Copy column A-C
3. Paste it always next the other, so DEF GHI KLM NOP (needed to feel the
performance degradation; so create more if you want to wait longer.. less if
you want to wait sorter.. 
4. Insert a row -> 3 seconds -> create more columns; not really difference
5. Delete the row -> 7 seconds -> This tends to decrease with more columns
6. Undo the delete of a column -> 10 seconds -> This tends to decrease with
more columns
7. Now repeat step 4/5 with tracking changes 
* Inserting 2 seconds (faster?)
* Deleting 5 seconds (faster)
* Manage track changes reject -> 6 seconds

Note replace rows for columns.. and the idea is the same

Actual Results:
delete and undo slow compared to insertion and in comparison with tracking
changes  enabled

Expected Results:
Equal to tracking changes enabled..and maybe even optimize tracking changes
delete/reject (also showing the 'same' speed decrease trend. Does needs a
double the amount of column to be annoying; again some quadratic decrease..
only starting with a lower number?)
