Is BASE not quoted or braced because it is a single word with no escape
type chars? Why is LOCKDIR in braces? Why are quoted UNnecessary?

As far as I know, it is always safe to use braces. Possibly the script
was written by two or more people, or the author had previously written
something that required braces, such as ${LOCKDIR:-default}
