In exceptional cases (custom installation, malfunctions elsewhere), `pyenv-commands --sh` may return nothing. In non-Fish, this would cause "syntax error near unexpected token `)'" in `pyenv()`. Bash does not allow to specify a `case` option that would never match. This works around it by defaulting to `/`. Commands, being filenames, can never match it. In Fish, nothing needs to be done: it apparently does interpret a `case` without argument as one that never matches.
