Patch for a completely rewritten file detected by the -B flag was shown as a pair of creation followed by deletion in earlier versions. This was an misguided attempt to make reviewing such a complete rewrite easier, and unnecessarily ended up confusing git-apply. Instead, show the entire contents of old version prefixed with '-', followed by the entire contents of new version prefixed with '+'. This gives the same easy-to-review for human consumer while keeping it a single, regular modification patch for machine consumption, something that even GNU patch can grok.

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.
