It indeed is that "add -N" appears only once in our test suite and
tests around it is lacking, but I'd prefer to see i-t-a to be taken
as just one of the normal things by not adding a special test for
it.  I wonder if there is a reason why these are not part of say
t4013 (diff-various)?

By adjusting and adding to existing test, we'd avoid a mistake of
adding a test script that is not executable (didn't your "make
DEVELOPER=1 test" catch the error?) ;-)

Thanks.
