Here is part of the ODF spec that might be relevant for that change:

6.1.2 White space Characters
Consumers shall collapse white space characters that occur in
? a <text:p> or <text:h> element (so called paragraph elements), and
? in their descendant elements, if the OpenDocument schema permits the inclusion of character
data for the element itself and all its ancestor elements up to the paragraph element.
Collapsing white space characters is defined by the following algorithm:
1) The following [UNICODE] characters are normalized to a SPACE character:
?HORIZONTAL TABULATION (U+0009)
?CARRIAGE RETURN (U+000D)
?LINE FEED (U+000A)
?SPACE (U+0020)
2) The character data of the paragraph element and of all descendant elements for which the
OpenDocument schema permits the inclusion of character data for the element itself and all its
ancestor elements up to the paragraph element, is concatenated in document order.
3) Leading SPACE characters at the start of the resulting text and trailing SPACE characters at the
end of the resulting text are removed.
4) Sequences of SPACE characters are replaced by a single SPACE character.
