After some settings (like installing other plugins and defining some mappings), I've found that GitGutter's Next Hunk (`]c` and `[c`) doesn't work any more.

If I do `]cabc` I will see `:<C-U>execute v:count1 . 'GitGutterNextHunk'<CR>abc`in the command, which means the mapping resulted in entering the text in command directly.

When I do `:map` I see `]c` correctly mapped to `<Plug>GitGutterNextHunk`, which is then mapped as:

```
n  <Plug>GitGutterNextHunk * &diff ? ']c' : ":<C-U>execute v:count1 . 'GitGutterNextHunk'<CR>"

```

Btw, calling directly like `:execute 'GitGutterNextHunk'` works. 

This all happens after I added the line `set cpoptions="aABceFsd"` to my `.vimrc`. I added the `d` for `tags` integration. How may that interfere with my mappings?
