fzf key bindings in fish not enabled automatically

[ekovarski]

The instructions during port install are not sufficient to enable the key bindings.

While fish will source the file, ${prefix}/share/fzf/shell/key-bindings.fish, as per the instructions when added to config.fish, the bindings have to be manually enabled by adding the following to ~/.config/fish/functions/fish_user_key_bindings.fish

function fish_user_key_bindings

fzf_key_bindings

end

This can save some frustration for the user. The install script for fzf usually handles it for fish but it does not seem to be part of the port.
