Description:
When typing in cell the auto-fill feature misses some data typed in the same column above. Sometimes you have to type the whole word, despite the same word was typed above. In the previous version of Calc (7.0) the auto-fill feature worked better, even with short two-character words - these were auto-filled correctly. 

Steps to Reproduce:
1.type words in several cells in the same column (especially short random abrevation as an ex. "AP", "PL", "RP").
2.save the file and reopen
3.in the same column type some same words used above




Actual Results:
Auto-fill works incorrectly, sometimes you have to manually fill the word used above, what makes auto-fill pointless. Auto-fill seems to work ok with words typed in the same session, but badly with words typed in the previous sessions or typed in a distant row. The auto-fill do not work after a typing a single character.

Expected Results:
Auto-fill should works as in the previous version of Calc. Even when a single character is typed the auto-fill should work.
