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. Signed-off-by: Junio C Hamano <junkio@cox.net>

test_description='Break and then rename
|
|
|
|
We have two very different files, file0 and file1, registered in a tree.
|
|
|
|
We update file1 so drastically that it is more similar to file0, and
|
|
then remove file0. With -B, changes to file1 should be broken into
|
|
separate delete and create, resulting in removal of file0, removal of
|
|
original file1 and creation of completely rewritten file1.
|
|
|
|
Further, with -B and -M together, these three modifications should
|
|
turn into rename-edit of file0 into file1.
|
|
|
|
Starting from the same two files in the tree, we swap file0 and file1.
|
|
With -B, this should be detected as two complete rewrites, resulting in
|
|
four changes in total.
|
|
|
|
Further, with -B and -M together, these should turn into two renames.
