Sorting order for filename completions, for :find, is broken

[alexaandru]

Sorting order of filename completions for :find is mangled, by having a subset of them be prefixed with ./ and thus, appearing at the top.

• vim -u DEFAULTS (version: ) behaves differently?
  No, I can reproduce the issue with both -u DEFAULTS and -u NONE.

• Operating system/version:
  Ubuntu 20.04.1 LTS

• Terminal name/version:
  kitty 0.15.0

• $TERM:
  xterm-kitty

Steps to reproduce using nvim -u NORC

$ git clone https://github.com/neovim/neovim.git
$ cd neovim
$ nvim -u NONE
:find <tab>
:set path=**
:find <tab>

the above is just an example, I can reproduce the issue with any number of repos.
There doesn't seem to be any pattern for which files are picked to be prefixed with ./... (at least I haven't found any).

Actual behaviour

Some of the completions are prefixed with ./ and thus appear at the top of the list.

Expected behaviour

That no completions are prefixed with ./ so that they are all properly sorted.

may be worth reporting to vim and we will eventually port the patch.

Sure, I can do that, thank you!
