Issue 90495

I start with a blank spreadsheet.  If I enter something that looks like a date,
it gets reformatted: eg entering 1 jan 2000, results in the cell showing 01/01/00. 

I would like to have control over which edit mask is used as the default, eg set
up D-MMM-YYYY as my preferred format.

I know I can change the format afterwards, but would prefer that all the dates I
enter start off in my preferred format.

I want to be able to set my preferred default for any one of the Format Cells /
Numbers / Categories, e.g. set up the default so that "currency" showing
negative numbers in black, and times don't display the seconds part of the time
i.e. HH:MM rather than HH:MM:SS as at present.  I'm guessing this might be best
done in association with the Template file

I'm guessing this could be of advantage also to dealing with any regional
differences in displaying cells.
