	- remove some of the uses of upstream/downstream DoNotStayInBlock

        * khtml/editing/markup.cpp:
	(khtml::createMarkup): Instead of using upstream to decide if a	line break should be
	added at the end, use inSameParagraph.
        * khtml/editing/selection.cpp:
        (khtml::Selection::debugPosition): Remove the code to print upstream and downstream,
	the selection endpoints themselves are adequate for debugging and are what we use for
	layout tests.
        * khtml/xml/dom2_rangeimpl.cpp:
        (DOM::RangeImpl::editingStartPosition): Skip a possible paragraph break at the start
	of the selection in a more explicit way to avoid DoNotStayInBlock.
