This possibly improves the usability of chattr for some typical use cases:

Command         : Old  : New behavior
================================================
chattr -h       : help : help
chattr -h FILE  : help : chattr -- -h -- FILE
chattr -hs FILE : help : chattr -- -h -s -- FILE
chattr -sh FILE : fail : chattr -- -s -h -- FILE
chattr -ar FILE : fail : chattr -- -a -r -- FILE

Unrelated: there a two trivial block-copied-but-not-changed issues:

$ egrep 'ACL|--r' chattr.c
           "Get POSIX ACL information\n"
       "  -R, --recursive     recursively list attributes of directories 
and their \n"
