Follow-up Comment #12, bug #38474 (project findutils):
> In the case of -perm, there is no existing file mode.
Sure, but POSIX says that find should treat the existing file mode as 0 here.
For example, POSIX says that "find /tmp -perm +rw" finds all files under /tmp
that are read-write to everyone and that have no other permissions. Admittedly
"+rw" means the same thing as "=rw" here, and "=rw" is clearer; but the point
is that there's good precedent for saying that 'find -perm' should mimic
chmod's syntax, even when the syntax is obscure.
