env parsing issue #104
Description
Since I also have the error that is described in #77 I searched further through the logs and figured that there must be wrong in parsing my local env with asdf.
I could find that my process is dying:
10:29:21.220 [error] Process #PID<0.173.0> terminating

While checking manually with iex what the code does it turns out that https://github.com/elixir-lang/expert/blob/main/apps/expert/lib/expert/port.ex#L77 under some condition will have an empty "" which then fails on matching with the [key, value].
I was able to find that after getting the env from the system that I have on some point 2 \n which then after splitting by that newline will lead to that empty string and subsequent in failing.
Unfortunately I wasnt able to find out where those 2 \n come from since my regular linux env seems to be ok and does not show anything that could explain this.
Maybe someone got an idea or further insight?
