that anyOrderedListStart did not check for a space following the
ordered list marker. So, 'A.B. 2007' would be parsed as a list item,
then fail because of the lack of space after 'A.' (required by
orderedListStart). Resolves Issue #22.
+ Fixed a similar problem in RST reader.
+ Added regression test.
