Description Brian Candler 2000-08-04 14:50:00 UTC 
cmp gives an exit status of 1 when comparing two identical files, in
the case where one is given on stdin (-) and the -s flag is also given.

(Aside: this breaks 'make check' for courier-imap)

How-To-Repeat: $ cmp -s /etc/passwd /etc/passwd
$ echo $?
0
$ cat /etc/passwd | cmp - /etc/passwd
$ echo $?
0
$ cat /etc/passwd | cmp -s - /etc/passwd
$ echo $?
1
