Respect < whitespace > tags in pasted HTML text (end the run-on pasted line)
When pasting formatted HTML text into ON, it all runs into one line. This is because most of the HTML clipboard programs use the WHITESPACE tag to control line breaks. ON doesn't appear to respect that particular tag, which leads to pretty awful formatting when using most of the HTML copy utilities.

This is easily repro'd by using Notepad++ to format some sample code (c++ for example), then using the NppExport plugin to copy it as HTML and pasting into OneNote.
