Those were my thoughts as well. And beyond that, even: why is there a "string" stored in "tmp_var" that needs to be included in one's interactive shell prompt, that can't be placed directly into PS1 in an appropriately quoted form? PS1 is normally a thing that one *controls*. Not something that's formed by random data coming from the environment, PWD excepted.
