cd command file discovery

[gelbi123]

What mechanism causes Helix try to discover ".git", ".gitignore", ".ignore" etc. files
on the "cd" command?

I stumbled around it when I navigate into big and sshfs mounted
that the auto-completion and keyboard typing really slows down...

So I straced it and it seems that in all subdirectories Helix is looking
for these files during typing the path after "cd"

Greetings and thanks ;-)
