And of course, '!' and '=' are not in the set of characters that crypt can
emit for an encoded password, so it is legit to write:
    =           empty password
    =!foo       clear-text password starts with a '!'
    ==bar       clear-text password starts with a '='
    !=          empty password                       , login is disabled
    !=!foo      clear-text password starts with a '!', login is disabled
    !==bar      clear-text password starts with a '=', login is disabled
