Keep line order in non fuzzy mode

[darkangel-ua]

When we set fuzzy = false it's would be great to keep lines in orders they are appear in file/buffer/source.
This will mimic grep like behavior.

I would not always enable it for fuzzy=false, i would implement it as separate option.

We could improve performance by swapping out functions, which would remove 1 if.

And i even think we can implement this on telescope.nvim sorter level.

Its a good idea thought, thanks :) If you are interested in trying the last point, feel free to say so, we could do a guided PR over there.

this is solved on telescope level, latest master

require("telescope.builtin").oldfiles {
  tiebreak = function(current_entry, existing_entry, _)
    return current_entry.index < existing_entry.index
  end
}

i prefer not to implement this here
