Fish config.fish: adding source (jenv init -| psub) causes shims dir to be added to path twice

[aholland]

I have changed the initialisation line in my config.fish file from
source (jenv init -|psub)
to
source (jenv init -| tail -n +2 | psub)
to prevent ~/.jenv/shims from being added to my path twice.

As soon as jenv is called it adds the dir to the path, and then the first line produced by jenv init - does it again. Here is the output of jenv init -:

set -gx PATH '/Users/anthonyholland/.jenv/shims' $PATH
set -gx JENV_SHELL fish
set -gx JENV_LOADED 1
set -e JAVA_HOME
set -e JDK_HOME
source '/opt/homebrew/Cellar/jenv/0.5.6/libexec/libexec/../completions/jenv.fish'
jenv rehash 2>/dev/null
jenv refresh-plugins
function jenv
  set command $argv[1]
  set -e argv[1]

  switch "$command"
  case enable-plugin rehash shell shell-options
    jenv "sh-$command" $argv | source
  case '*'
    command jenv "$command" $argv
  end
end

@aholland Thanks for this fix. The duplicate $PATH entry had been bugging me too.

Might be good to submit a PR to get this corrected in the README.

Also wonder if those instructions should use fish_add_path instead, which might also help to prevent the duplicates. 🤔
