cache-archiver reports an overinflated number of matched files

Summary

gitlab-runner cache-archiver reports an overinflated number of matched files.

Steps to reproduce

Have a file structure like the following:

Directory path0
- Directory path1
  - Directory path2
    - Directory path3
      - file1
      - file2
      - file3
      - file4
      - file5
      - file6
      - file7
      - file8

Then run this:

gitlab-runner-windows-amd64.exe cache-archiver --verbose --file archive.zip --path path0/**

Actual behavior

I receive this output:

Runtime platform                                    arch=amd64 os=windows pid=6388 revision=b37d3da9 version=14.3.0
path0/**: found 38 matching files and directories
No URL provided, cache will be not uploaded to shared cache server. Cache will be stored only locally.

Expected behavior

It should display "found 12 matching files and directories" (8 files + 4 directories).

Environment description

No build logs or config.toml applicable, since it also happens when launching gitlab-runner directly.
