Why was 0x2E (US-ASCII), of many other available choices, used as a prefix for node names so as to make a distinction which could be used to hide them from usual directory lists?I ask because of the small conflicts with the '.' and '..' nodes which occur when globbing.  There are various protections in place which prevent renaming or damaging those two while using most system calls, but it nevertheless begs the question:  Why 0x2E?I would like to review some of the engineer's notes because I am selecting from other possibilities for mostly frivolous purposes.
What is the history of 0x2E (ASCII) as a prefix for filenames?
