o Removed two unused variables (f_dirname and f_newline) in ls.c

Browse Source 
o Added the -H and -P options for treatment of symbolic links.

o Removed the #ifdef BSD4_4_LITE, since it does not seem to do anything
  useful

o Fixed up prn_octal() so its output looks more like that of AT&T Unices
  when -b is given.

The next two lines apply only to the first two changes above:
