Bug 87612

The "Width" and "Spacing" fields in Writer's Format->Columns dialog perform checks after each character keyed.  This makes it impossible to type numbers beginning with a "."

Steps to reproduce:
1. Create a new document
2. Format -> Columns
3. Columns: 3
4. Highlight everything in the "Spacing" field (triple-click)
5. Type .8

Expected:
The spacing field should contain "0.80".  The validity checks for the number should be performed after we are finished typing our number. 

Actual:
Since the validity checks are performed as we type each character, our number is interpreted in a frustrating way.  The "." is thrown away.  The 8 is then used for the inch field, which is an impossible value with 3 columns.  So LO reduces our columns from 3 to 2, and shrinks our width to "3.44".

Notes:
If you know what's going on, it is easy enough to work around this issue.  Unfortunately, most users won't understand this behavior and will be extremely frustrated by the seemingly random values and changes to column numbers.  No other fields in dialogs update in this manner, that I've found.  The easy work-around is to type the leading 0.  Typing "0.8" does get around this bug.

Also, why does the column width change our set number of columns?  That field should be left alone.

Also, if we follow the example above, but then try to correct our mistake by typing in "0.8" the second time, our columns will still show that they've been reduced to 2, but the picture will go back to displaying 3 columns.  It will insert 3 columns when we hit ok.

This appears to have been introduced in 4.3.x, but does not affect 4.2.x.
