Neovim version

NVIM v0.8.3
Build type: RelWithDebInfo
LuaJIT 2.1.0-beta3

Operating system and version

Ubuntu 20

4222bb8

Minimal config

Any config that enables nvim-tree is fine

Steps to reproduce

Looks like more than 32 levels triggers it

1. mkdir -p _/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_
2. cd _/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_
3. touch test.txt
4. nvim
5. :NvimTreeOpen

Expected behavior

Directory opens

Actual behavior

crashes. added some prints in path_relative

Perhaps path_to_matching_str doesn't need to capture the substitutions?

function M.path_to_matching_str(path)                                                                                                                                                            
     return path:gsub("(%-)", "(%%-)"):gsub("(%.)", "(%%.)"):gsub("(%_)", "(%%_)")
end

Should it be ?

function M.path_to_matching_str(path)                                                                                                                                                            
     return path:gsub("(%-)", "%%-"):gsub("(%.)", "%%."):gsub("(%_)", "%%_")
end

This fixes the issue for me
