Prepending a count breaks j and k
In the gundo window, j and k move up and down between undo states, which are actually 2 lines apart. If you prepend a count, things don't behave the way you would expect. I noted the following behaviour:
j = 1j = 2j 3j = 4j 5j = 6j etc... k = 1k 2k & 3k do nothing 4k = 5k = down one 6k = 7k = down two 8k = 9k = down three etc...
Not a show stopper, but it would be nice to be able to move quickly by prepending a count to j/k keys.
