(The reference here is to the fact that only the lowest 8 bits of n
are used.)

Existing programs almost never use anything other than a return code of
0, 1, or 2.  It almost doesn't matter what the standard says about the
number of bits used.  In fact the standard could simply have said:
"...if the value of the exit code is not 0, 1, or 2, it is interpreted
in an implementation-dependent manner".  That would not affect more
than about 0.2% of existing C programs.  The current standard affects
all of them.
