In Red Hat 7.1 and prior releases, as well as in other Unixen, attempting
to run more on a file which the user does not have permission to access
results in the logical error message "permission denied."

Some time during the betas, this was broken.  more now reports "illegal
seek" when users try to use more as a page for files for which they don't
have read permission.

This is a regression from prior releases.

RH 7.1:

[kaboom@hanuman kaboom]$ ls -l /tmp/foo
-rw-------    1 root     root        12636 Sep  3 22:49 /tmp/foo
[kaboom@hanuman kaboom]$ more /tmp/foo 
/tmp/foo: Permission denied
[kaboom@hanuman kaboom]$ id
uid=500(kaboom) gid=500(kaboom) groups=500(kaboom),10(wheel)
[kaboom@hanuman kaboom]$ 

RC2:

[kaboom@verdande kaboom]$ ls -l /boot/grub/grub.conf 
-rw-------    1 root     root          667 Aug 31 19:36 /boot/grub/grub.conf
