As far as I understand, now you can't redefine actions for :Commits/:BCommits without changing fzf.vim/autoload/fzf/vim.vim, am I correct?
If so -- and since :Commits relies on the external dependency, vim-fugitive, which may or may not be installed -- it would be great to allow users to set the sink actions via some configurable variable may be? And if no such variable is defined, then use the default predefined sink, s:commits_sink().
What do you think?
