"E492: Not an editor command" via show_cursor

This is similar to issue #1:

I am trying to debug where a "no mapping found" message is coming from and have started Vim with `-V5`.

When searching in `:Redir mess` then, I get the following error after pressing Enter to search:

```
/no mapping
highlight link Cursor VisualNOS^@^ILast set from ~/.dotfiles/vim/neobundles/pseudocl/autoload/pseudocl/render.vim
Error detected while processing function 50_oblique..pseudocl#start..pseudocl#render#loop..158_show_cursor:
