[PATCH 3/6] fish-completion: support completions for wrapper commands

[Johannes Altmanninger]

There is no point to checking the command name, fish already does that.
Additionally fish knows about commands that "wrap" pass; those commands
should inherit pass's completions.

This commit enables fish>=3.1.0 to provide proper completions for this function:

	alias p="PASSWORD_STORE_DIR=$HOME/.my-passwords pass"

or, equivalently,

	function p --wraps "PASSWORD_STORE_DIR=$HOME/.my-passwords pass"
		PASSWORD_STORE_DIR=$HOME/.my-passwords pass $argv
	end
