Junio C Hamano 2bbcddee87 Adjust diff-raw tests to the status letter change.
We use 'A' for added files instead of 'N' to make the it
visually easier to distinguish from 'M' now.

While we are at it, make the test scripts executable.  Yes, I
know it does not matter because t/Makefile runs them explicitly
with "sh tXXXX-blah.sh", but being consistent is always better.
