Ran into a small oddity with Dir.glob and how it matches dotfiles. Looked into it: not matching hidden files is standard behavior and one has to use the option dot_files to get hidden file to match. Ok. However:
* │ [“subdir”] - doesn’t match .hidden
*/ [“subdir/”, “.hidden/”] - DOES match .hidden/
This inconsistency is why **/*/.gitignore “works” - when * is followed by /, it inexplicably matches dotfiles.
I don’t think I understand what your examples are supposed to mean. I can’t understand the notation.
Could you perhaps clarify the cases in text?
This was motivated from the code that was removed in Use match: :dot_files for glob instead of workaround · trans/ignoreme@26a1914 · GitHub
Dir.glob("*") # does not match hidden paths (standard behavior)
Dir.glob("*/") # does match hidden paths
Dir.glob(“*/”) is match with sub-directory in current folder, even though it does seem a bit inconsistent, a directory is also a file technically.
Ah, gotcha 
This looks like a bug, actually. */ should not match .dir/, just like * doesn’t match .file.
