scp doesn't seem to work, both machines use fish. Tried running in and outside tmux.

Reproduction Steps:

1. scp remote-host:remote-file . (remote host uses fish)

Expected behavior:

Download of file.

Observed behavior:

fish: Could not set up terminal
fish: src/env.cpp:915: const wchar_t* env_var_t::c_str() const: Assertion `! is_missing' failed.

Additional information:

I'm on a fairly barebones void linux install and have been getting a lot of funny hiccups because of commonly assumed programs not being installed, though this looks like a problem with fish.

Fish version: 2.3.0

Operating system: Void Linux (musl)

Terminal or terminal emulator: tmux and st.

For 2.3.1 release:
