Re: [PATCH v3 0/3] dir: treat a repository without commits as a repository

Kyle Meyer [off-list ref] writes:

The series improves the handling of sub-repositories that don't have a
commit checked out.  In particular, it addresses the following issues:
...
  * Commit message tweaks.  These include replacing wording like "no
    commits" with something like "no commit checked out" because,
    technically, this series also concerns repositories that have
    commit objects but are on an unborn branch.

Changes from "not have any commits" to "not have a commit checked
out" can also be seen in the code (the next bullet point), which is
a very welcome change.  It shows that the patchset was done with
nice attention to the detail.

  * Change the "git submodule add" error message to match the wording
    of the new error message added in add_to_index().

  * Consistently use "expect" rather than "expected" as the output
    file name for expected test output.

Thanks; will replace.  Hopefully this round is ready for 'next'.
