	Where does this show up in the standard?  I've looked in the
	entry for 'pathname resolution' (IEEE Std 1003.1-1988, Chapter
	2.4, p. 36) and can find no such exception described.

	The only relevant requirement I found says "If the pathname
	begins with a slash, the predecessor of the first filename in
	the pathname is taken to be the root directory of the process[.]"

	Since a filename may not contain a slash, this means that
	two leading slashes are equivalent to a single slash.
