	Problem: Some tests fail with $SHELL=fish #6172 Related: https://github.com/neovim/neovim/pull/6176 Solution: Replace "echo -n" with "printf", because "echo" in sh may be provided as a shell builtin, which does not accept an "-n" flag to avoid a trailing newline (e.g. on macos). "printf" is more portable (defined by POSIX) and it does not output a trailing newline by itself. Fixes #6172 TODO: Other test failures may be related to "session leader" issue: https://github.com/neovim/neovim/issues/2354 Checked by running `:terminal ./build/bin/tty-test` from Nvim with `shell=/bin/fish` (inherited from `$SHELL`) and it indeed complains about "process does not own the terminal". With `shell=sh` it doesn't complain. And unsetting `$SHELL` seems to make `nvim` to fall back to `shell=sh`.
