They changed it to zeros later, because a zero is much more powerful.
For example, leading zeros can be very powerful, expecially when  you
employ  them  in  the  management  of big companies. [BTW: that's the
difference between commercial  and  scientific  notation:  scientists
tend  to  suppress  leading  zeros.]  And, to quote an ancient usenet
posting (sorry, the exact source is unknown to me):

Zero is an enigmatic value. It can mean success (fclose)  or  failure
(scanf).  It  can  mean  black  or  white. It can mean no permissions
(chmod) or all permissions (umask). It can mean now (setjmp) or later
(atexit). It can mean the beginning (lseek) or the end (read). It can
mean myself (getpgrp) or child (fork). It can mean  all  (kill's  1st
argument)  or  nothing  (kill's  2nd argument). It can mean `default'
(SIG_IGN) or `I don't care' (waitpid) or  `try  to  guess'  (strtol).
Indeed 0 lets you talk to God (setuid).
Verily is 0 all things to all people.

SCNR :-)

As usual, this being a 1.3.x release, I haven't  even  compiled  this
kernel yet. So if it works, you should be doubly impressed.
