Append/Prepend error/bug in Ruby Gem, adding a " (double quote) character on each append, sometimes more than one, unless :format => :plain is used on every operation (but that should be the default)

gistfile1.rb

cb = Couchbase.connect

cb.set("mylist", "oranges", :format => :plain)

puts cb.get("mylist").to_s
# =>  oranges

cb.prepend("mylist", "apples,")

puts cb.get("mylist").to_s
# => "apples,"oranges

cb.append("mylist", ",bananas")

puts cb.get("mylist").to_s
# =>  "apples,"oranges",bananas"

cb.append("mylist", ",lemons")

puts cb.get("mylist").to_s
# =>  "apples,"oranges",bananas"",lemons"

cb.append("mylist", ",grapes")

puts cb.get("mylist").to_s
# =>  "apples,"oranges",bananas"",lemons"",grapes"



cb = Couchbase.connect

cb.set("mylist", "oranges", :format => :plain)

puts cb.get("mylist").to_s
# =>  oranges

cb.prepend("mylist", "apples,", :format => :plain)

puts cb.get("mylist").to_s
# => apples,oranges

cb.append("mylist", ",bananas", :format => :plain)

puts cb.get("mylist").to_s
# =>  apples,oranges,bananas

cb.append("mylist", ",lemons", :format => :plain)

puts cb.get("mylist").to_s
# =>  apples,oranges,bananas,lemons

cb.append("mylist", ",grapes", :format => :plain)

puts cb.get("mylist").to_s
# =>  apples,oranges,bananas,lemons,grapes
