+	This option specifies a function to be used to handle any registers
+	that Neovim does not natively handle. This option unlocks all
+	characters to be used as registers by the user.
+
+	The 'userregfunc' function is called each time a user register is read
+	from or written to.
+
+	The 'userregfunc' function must take the following parameters:
+
+		{action} The action being done on this register (either 'yank'
+			or 'put'
+
+		{register} The string holding the name of the register. This
+			is always a single character, though multi-byte
+			characters are allowed.
+
+		{content} If the action is 'yank' this is the content being
+			yanked into the register. The content is a dictionary
+			with the following items:
+
+			{lines} The lines being yanked, as a list.
+
+			{type} The type of yank, either "line", "char", or
+			"block"
+
+			{width} The width in case of "block" mode.
+
+			{additional_data} Additional data. (can be returned in
+			put mode).
+
+	In case the action is 'put', the 'userregfunc' function should return
+	the content to place in that location. The content can either be a
+	string, in which case "char" mode is inferred, or it can return a
+	dictionary of the same template that populates 'content'.
+
+	A very simple example of a 'userregfunc' function that behaves exactly
+	like traditional registers would look like: >
+		
+		let s:contents = {}
+		function! MyUserregFunction(action, register, content) abort
+		   if a:action == "put"
+		     return get(s:contents, a:register, "")
+		  else
+		     let s:contents[a:register] = a:content
+		  endif
+		endfunction
+		set userregfunc=MyUserregFunction
