Subject: [BUG] git-mv submodule failure
Message-ID: <46dff0320710192301p3e1d88d5l3b662b72b051d920@mail.gmail.com>

project
  .git
  file1
  submoudle
     .git
      file2

$ cd project
$ git-mv submodule submodule1
fatal: source directory is empty, source=submodule, destination=submodule1

However, the following is ok and rename is automatically detected
$ cd project
$ mv submodule submodule1
$ git-add submodule1
$ git-commit -a

which gives in vim:
# Please enter the commit message for your changes.
# (Comment lines starting with '#' will not be included)
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   renamed:    submodule -> submodule1
#
