Every so often, W3 would get into this annoying mood where it creates
a buffer called "stylesheet" and modifies it, thus making it show up
with, say, `save-some-buffers'.  I hate when that happens, especially
as the buffer doesn't show up in the regular buffer list.  So I did
this long ago and then forgot about it÷

	* lisp/css.el (css-parse): Set `buffer-file-name' to nil after
	reading stylesheet, to avoid spurious requests for saving the
	file.
