need some info on file command recommendations of the open group.

Hello,

 I need some help in interpreting the IEEE 1003.1 document. Given below is 
an abstract.
-----------------------------------------------------------------------------

17180 OPTIONS
17181 The file utility shall conform to the Base Definitions volume of 
IEEE
      Std 1003.1-2001, Section 12.2, Utility Syntax Guidelines, except 
that
      the order of the -m, -d, and -M options shall be significant.
     ...

17198 If the -m option is specified without specifying the -d option or 
the -M
      option, position-sensitive default system tests shall be applied 
after
      the position-sensitive tests specified by the -m option. If the -M 
option
      is specified with the -d option, the -m option, or both, or the -m
      option is specified with the -d option, the concatenation of the
      position-sensitive tests specified by these options shall be applied 
in
      the order specified by the appearance of these options. If a -M or
      -m file option-argument is -, the results are unspecified.
---------------------------------------------------------------------------------------------------
If I say:-
# file -d -m <magic file1> -d -M <magic file2> test.c
does this not mean that default tests will be applied to test.c first?
The default test will state that this is a C file.

What exactly does this term "concatenation of position-sensitive tests" 
imply (if not the above result)?

thanks
