If you don't use any scope/export options with set and fish finds an
existing variable with the specified name, it assumes you'll want to change
that. If you do use a scope option like -g, fish will create a global PATH
alongside the universal PATH. And as it is a new variable created without
the -x flag, it will not be exported. So that's why PATH doesn't change. I'm
not sure why it works on a login shell though.
