diff-tree -r and new directories

In one of my scriptlets I have this:

   git diff-tree -r --name-only --diff-filter=AM -z "$rev" HEAD --

and I had assumed that only files would ever be listed because of the -r switch. But this is not true: If there is a new directory, it lists only the directory's name instead of the files. Is this the intent? Is it worth changing?

Hmm. you would need a better reproduction recipe than that.

    $ git init
    Initialized empty Git repository in .git/
    $ >file
    $ git add file
    $ git commit -a -m initial
    Created initial commit 2f9da65: initial
     0 files changed, 0 insertions(+), 0 deletions(-)
     create mode 100644 file
    $ mkdir new
    $ >new/file
    $ git add new/file
    $ git commit -a -m second
    Created commit a1fa8fb: second
     0 files changed, 0 insertions(+), 0 deletions(-)
     create mode 100644 new/file
    $ git diff-tree -r --name-only --diff-filter=AM -z HEAD^ HEAD |
      tr '\0' '\n'
    new/file
    $ git diff-tree --name-only --diff-filter=AM -z HEAD^ HEAD |
      tr '\0' '\n'
    new

Perhaps you somehow did not have "-r" even though you thought you had?

Heh. It turns out that the questionable directory is actually versioned by git. My scriptlets have added it as a submodule while I looked in the other direction:

  $ git diff --summary $rev.. -- . | cat
  create mode 160000 D/Project/foo

:-) Problem solved. Thank you.
