Parentheses create a subcommand context -- not a new file or function
context. So when you do `(status current-function)` fish looks walks up the
execution context stack till it finds a function frame and uses that to
extract the function name. Same for `(status current-file)`. What should
`(status current-line)` do? What stack frame should it use? That question
is basically the crux of
https://github.com/fish-shell/fish-shell/issues/4161. Feel free to comment
on that issue.
