Tutorials like mw:Help:Formatting state that a single new-line will have no effect, however, that is not always the case. Single new-lines after block-level HTML elements might result in unnecessary <p> tags being created: while <div>foo</div> results in just that, <div>\nfoo\n</div> will result in <div><p>foo</p></div>. This can be very confusing because some CSS attributes of the div tag will have no effect (they will be overwritten by <p> rules in some CSS file). See the link for an example.
