We would probably want to say that status symbol is an uppercase
alpha [A-Z]. Or maybe limit it to a non-whitespace letter (\S).
Dot there to say "just any letter" looks wrong.
I would use "+" instead of hardcoding the length of mode strings
(you have 6 there) and object name hash (ditto 40) but that is
mostly style and a slight future proofing against us using
longer hashes (not in our immediate future though).
