The title of this option is accurate but easily misunderstood. It isn't so much about changing how the characters are interpreted, i.e., non-true uses "*" while true uses ".*" but rather where regex interpretation takes place. We leave it disabled because we do not want all of our strings interpreted as regular expressions.
Then again, maybe this is why we have found Nagios regex a little inconsistent. I wonder how it delimits a string. I would view: abc.*(?:def|ghi|jkl) as a string but perhaps Nagios thinks the only regex is abc.* -- John A.
