Iterates over and yields a new Pathname object for each element in the given path in descending order.
Example
Pathname.new('/path/to/some/file.rb').descend {|v| p v} #<Pathname:/> #<Pathname:/path> #<Pathname:/path/to> #<Pathname:/path/to/some> #<Pathname:/path/to/some/file.rb> Pathname.new('path/to/some/file.rb').descend {|v| p v} #<Pathname:path> #<Pathname:path/to> #<Pathname:path/to/some> #<Pathname:path/to/some/file.rb>
Returns an Enumerator if no block was given.
enum = Pathname.new("/usr/bin/ruby").descend
# ... do stuff ...
enum.each { |e| ... }
# yields Pathnames /, /usr, /usr/bin, and /usr/bin/ruby.
