Restore and clarify config_version functionality

This branch is intended as a portability fix. Some functionailty had
been inadvertently removed as unused, but testing revealed that it had a
purpose. Because the purpose was unclear, this commit restores the
functionality AND clarifies it in the script names and comments in
config_version.sh.
