Use a negative limit on the split to stop it stripping trailing empty
fields:

irb(main):018:0> "/dir/".split("/")
["", "dir"]
irb(main):019:0> "/dir".split("/")
["", "dir"]
irb(main):020:0> "/dir/".split("/", -1)
["", "dir", ""]
irb(main):021:0> "/dir".split("/", -1)
["", "dir"]
irb(main):022:0> "/dir/".split("/", -1).join("/")
"/dir/"

Hope this helps,

Mike
