* buffer.c (Fbury_buffer): This used to undisplay the buffer being

	buried only if the BUFFER argument was nil.  Instead, undisplay the
	buffer whenever it's displayed in the selected window, no matter
	how it was specified by BUFFER.  This is how it behaves in 18.58,
	and I can't find any ChangeLog entry in 18.58 or 19.0 saying why
	they differ.  Fix the doc string accordingly.
