Subject: [PATCH] Prefer 'set' over 'setenv' for fish shell

The setenv function in fish shell has changed dramatically in
https://github.com/fish-shell/fish-shell/commit/75600b6b538f242a6b340e51965f25cfd4473c4a
It now conforms to the csh version, which takes at most two arguments.
In this init script, the form
    setenv PATH prepend_something $PATH
had been used, which had too many arguments.
Since setenv isn't a native command in fish, a suitable replacement is
to use the "set -gx" command, which can consume multiple arguments.
