passwd help/version patch

[Joshua Daniel Franklin <joshuadfranklin at yahoo dot com>]

Here is the --help, --version patch for passwd.
I used the idea from a recent cygpath patch to separate usage output into
sections, though I feel I've improved on it a bit. :)
Corinna, you might want to take a look at these longopt names I chose to
make sure they're OK:

Usage: passwd (-l|-u|-S) [USER]
       passwd [-i NUM] [-n MINDAYS] [-x MAXDAYS] [-L LEN]

User operations:
 -l, --lock      lock USER's account
 -u, --unlock    unlock USER's account
 -S, --status    display password status for USER (locked, expired, etc.)

System operations:
 -i, --inactive  set NUM of days before inactive accounts are disabled
                 (inactive accounts are those with expired passwords)
 -n, --minage    set system minimum password age to MINDAYS
 -x, --maxage    set system maximum password age to MAXDAYS
 -L, --length    set system minimum password length to LEN
