Previously, in Calc CSV export, all content from text cells was quoted
with the selected text delimiter. Now this is optional and happens
only if the new check box "Quote all text cells" is selected. By
default, the text delimiter is added only if the cell content contains
the field delimiter, text delimiter or multiple lines.
When a CSV file is loaded and saved again without editing the filter
settings, the import option "Quoted field as text" is used for the
"Quote all text cells" option. The default for "Quoted field as text"
is now "off" (but if it's changed in the import dialog, that is still
saved as new default in the configuration).
