splice.vim: Unknown function: splice#SpliceInit at launch

Hi there!

I installed Splice.vim through Vundle but I got these error when running git mergetool. Here is my .gitconfig:

[merge]¬                                                                         
▸   tool = splice¬                                                               
[mergetool "splice"]¬                                                            
▸   cmd = "vim -f $BASE $LOCAL $REMOTE $MERGED -c 'SpliceInit'"¬                 
▸   trustExitCode = true

Nothing original as you can see.

Any idea?
