Pgup with freeze needs some fine tuning

Description

Say you have a few pages worth of row data - say 50 rows. And you have a freeze betwen row 3 and 4.

I have my cursor in A1 and then a I use the down cursor to get to cell A50. I hit pgup twice and instead of seeing the clean home page view of row 1 to 36 inclusive (my zoom and row sizes allow me to see 36 rows), I see row 1,2,3 and then 17,18, etc.

Looks like a corner case for the pgup handling routine that needs to be adjusted.

This is on gnumeric 1.2.8 running on FC2 latest code.
