Hmm.  macros.h defines SIZEOF, and test-argv-iter.c defines
ARRAY_CARDINALITY, both of which are used to determine the size of an
array.  I kind of prefer the name in test-argv-iter (to me, sizeof implies
a size_t count of bytes, not the number of elements).  Is it okay to
rename the macro in macros.h to ARRAY_CARDINALITY, adjust all callers, and
to simplify test-argv-iter?
