Multi-Line in one cell Issue

[heefan <heefan gmail com>]

Hi guys,

I found a issue about multi-line in one cell.
Firstly shortcut key Alt-Enter is not working.
Second, I selected one cell and right-click to 'Format 1cell'. And then 
I tick 'Wrap Text'. It works.
But if I select all the cells or many  cells, and right-click to format 
all of them, I still some of the cells are not set.

My version is Gnumeric Spreadsheet 1.10.13, and Ubuntu11.04.

Thanks
Regards
