I have fixed them and simplified the PR. Please test it.

The problems are already fixed in vim HEAD.

@raghur You can test the PR. https://github.com/junegunn/vim-plug/pull/937

@mattn Ping.

@raghur Can you profile the vim-plug code? :help :profile

:profile func is needed. You need to research func name pattern.

Oh, git checkout is too slow in your environment.

 defx.nvim supports multi root feature.

I will add it later.

Updated.
