I don't understand what:
silent! call repeat#set("<Plug>MyWonderfulMap", v:count)
means. Am I supposed to replace <Plug> and/or MyWonderfulMap with something else, and if so what?
I tried:
silent! call repeat#set("surround", v:count)
but it had no effect.

Thanks for making this plugin!

I'd like to add that an explanation of the two parameters that the repeat#set function takes would be helpful. I looked at the source code for a couple of the plugins mentioned in the readme and it wasn't clear how they related to the documentation mentioned above.

I found the documentation in the source code: https://github.com/tpope/vim-repeat/blob/master/autoload/repeat.vim#L19-L45
