Sorting mixes filesystem and flags

[TylerLeonhardt]

Testing #241771

The sorting feels a little weird here... it's some filesystem completions, then flags, then more filesystem.

I feel like flags and such would be better on top.

Since sorting occurs as a user types, I don't think this is a big deal.

I think we boost . and ../ here specially here as we were optimizing for the file/folder path case, and ~ may be treated as the empty string since we ignore punctuation when sorting. Maybe you're right and flags should just always be above paths if they have the same score 🤔

I feel like there's gonna be a scenario where I want them at the top... but idk it looks weird to me. This feels like a good setting option though... reminds me of "snippets at the bottom of completions"... we have some settings around influencing the sort

[Tyriar]

We probably will never be able to make people happy, there's an argument for all flags to be at the bottom unless - is the prefix too🤷
