This is marked as unix-only but the dep is always added
However, should we support this on Windows?

I'm not sure if this feature should be supported on Windows, as it does not seem to be used on Windows.

Technically, there are other variants of ~ expansion. Should we support that?

I'm not sure about what they are, can you explain?

Why are we changing this to be more restrictive?

There doesn't seem to be a way for me to get &OsStr directly from String, maybe I should? (The reason for the change to String is that the replace_range method is only available for String)
let mut new_current = OsString::new();
new_current.write_str(¤t).ok();
let mut candidates = complete_path(&new_current, current_dir, filter);

Maybe I should have used let mut current = current.to_string_lossy().to_string(); ?

With std::env::home_dir being undeprecated, we should be using this through a polyfll. I'll need to go create one before this can move forward.

(if it wasn't for that, I'd be hesitant to add this out of question of whether the extra dep is worth it)

Perhaps we could copy that function from std? https://github.com/rust-lang/rust/blob/2682b88c526d493edeb2d3f2df358f44db69b73f/library/std/src/sys/unix/os.rs#L595
