NEWS entries are done.

I added a function, copy_strip, to help.py to rstrip (in bytes mode) idle.html as it copies to help.html.  (I changed the name to better remember which is which.)  In my .bat file, with Doc as current directory, I use
  ..\pcbuild\python_d.exe -c "from idlelib.help import copy_strip; copy_strip()"
I could change the if __name__ block so that
  ..\pcbuild\python_d.exe -m idlelib.help copy_strip
would work.  Either way, I would like to add 'idlehelp' to makefiles.  But not tonight.
