md5 goes from an arbitray length to a 128-bit message digest. Since
the output size is what matters for storage in /etc/master.passwd
(and it's always the same), you should be able to use however long
a password you like, provided it doesn't bump up against the end
of a buffer in login(1) or passwd(1). (It'll still get turned into
the same length digest, of course.)
