PmWiki uses the prefix 'passwd' on an attribute to indicate that
something is a password field and should be encrypted when saved to
disk.  

The complete set of steps to add a separate "diff" password 
to PmWiki would be:

    $PageAttributes['passwddiff'] = '$[Set new history password]';
    $DefaultPasswords['diff'] = '';
    $HandleAuth['diff'] = 'diff';
    $AuthCascade['diff'] = 'read';    ## or 'edit'

The first line adds a "history password" field to ?action=attr.
The second line indicates that 'diff' is a valid password, and
sets the site-wide diff password to no password.  The third
line tells ?action=diff that it's to use the 'diff' password
for authorization, and the last line says that if no 'diff'
password is set, use the 'read' password for the page.
