I just read the man-page, where it says:

  -perm mode
              File's  permission  bits  are  exactly mode (octal or
              symbolic).  Since an exact match is required, if  you
              want  to  use  this  form for symbolic modes, you may
              have to specify a rather complex  mode  string.   For
              example  '-perm g=w' will only match files which have
              mode 0020 (that is, ones for which group  write  per-
              mission  is  the  only  permission  set).  It is more
              likely that you will want  to  use  the  '+'  or  '-'
              forms,  for  example  '-perm -g=w', which matches any
              file with group write permission.  See  the  EXAMPLES
              section for some illustrative examples.

       -perm -mode
              All of the permission bits mode are set for the file.
              Symbolic modes are accepted in this form, and this is
              usually the way in which would want to use them.  You
              must specify 'u', 'g' or 'o' if you  use  a  symbolic
              mode.    See  the EXAMPLES section for some illustra-
              tive examples.

       -perm +mode
              Any of the permission bits mode are set for the file.
              Symbolic  modes  are accepted in this form.  You must
              specify 'u', 'g' or 'o' if you use a  symbolic  mode.
              See  the EXAMPLES section for some illustrative exam-
              ples.

And at least for my limited (non-native) understanding of english this ain't 
the same as the (not clearly written) POSIX-standard.

So maybe it's not find, but it's man-page which should be changed? Perhaps 
having a few examples and a better explanation?


Thank you!
