tar on a directory mydir will archive hidden files and hidden subdirectories, but tar from withinmydir with a * wildcard will not. Is this a known inconsistency or bug?
Edit: Additional information. tar from withinmydir with a * wildcard will not "see" nor archive hidden files and hidden subdirectories in the immediate directory. However, in the non-hidden subdirectories of mydir hidden files and hidden subdirectories will be archived. In other words, deeper in the directory tree the hidden objects will be archived.
