" Basic usage is as follows:
"
"   silent! call repeat#set("\<Plug>MappingToRepeatCommand",3)
"
" The first argument is the mapping that will be invoked when the |.| key is
" pressed.  Typically, it will be the same as the mapping the user invoked.
" This sequence will be stuffed into the input queue literally.  Thus you must
" encode special keys by prefixing them with a backslash inside double quotes.
"
" The second argument is the default count.  This is the number that will be
" prefixed to the mapping if no explicit numeric argument was given.  The
" value of the v:count variable is usually correct and it will be used if the
" second parameter is omitted.  If your mapping doesn't accept a numeric
" argument and you never want to receive one, pass a value of -1.
"
" Make sure to call the repeat#set function _after_ making changes to the
" file.
"
" For mappings that use a register and want the same register used on
" repetition, use:
"
"   silent! call repeat#setreg("\<Plug>MappingToRepeatCommand", v:register)
"
" This function can (and probably needs to be) called before making changes to
" the file (as those typically clear v:register).  Therefore, the call sequence
" in your mapping will look like this:
"
"   nnoremap <silent> <Plug>MyMap
"   \   :<C-U>silent! call repeat#setreg("\<lt>Plug>MyMap", v:register)<Bar>
"   \   call <SID>MyFunction(v:register, ...)<Bar>
"   \   silent! call repeat#set("\<lt>Plug>MyMap")<CR>
