First, I asked it in [ruby-core:5641].  The reply, [ruby-core:5660],
contains an implementation that the root directory is considered a
separate element.

Second, [ruby-core:5678] shows an example to search Rakefile.  It
seems that ascend is useful for searching /Rakefile if it yields /.

Note that I know current implementation has a problem with relative
pathnames.  Pathname.new("./a/b/c").descend doesn't yield ".".  I'll
fix it later.
