Add support for n N # * g* g#

[toombs-caeman]

if no count is given v:count is 0, which moves the cursor, making commands like n get stuck and N skip over matches on the same line.

v:count1 exists, but interferes with <C-D> and friends.

Also, because of :help function-search-undo, n won't re-highlight matches unless the relevant values are explicitly returned from the function and re-set.

I have been using @toombs-caeman fork for three months without any problems, in both vim and neovim.
n and N have such nice and smooth movement.
Maybe it's possible to consider this fork.
Thanks to both of you for such a good plugin... the best.
