disp_float_fmt ignored for showing row

[cool-RR]

When I press Enter on a CSV sheet to see a row as a sheet, it knows to type some values as floats, but why doesn't it use my display format for these floats? I've got disp_float_fmt set up to my favorite format but it's ignored in this scenario.

disp_*_fmt options are only for columns typed as such. We could expand the display engine to use the formatters for individual cells too; I can see that being useful.
