Would people prefer something simple like vms or a > fully-featured cvs-like system? VMS version control is problematic. It requires that patter expansion be done in the kernel, not in the shell. THere's a lot of other good reasons to do this, like not pushing non-matching file names over the user/kernel boundry unnecessarily. The problem with doing this is shell globbing. Shells expand patterns before they would be givent to the FS. This would be a significant deviation from the way It Has Always Been.
