It segfaults for me, since you try to strdup NULL. I think you want to
return "" if there is no initial commit, so you can strcmp against the
current committer (or alternatively, explicitly check for NULL).

Why strdup at all here, which leaks? Nobody else uses this variable, so
it should be sufficient to strcmp(get_parent_ident(), committer_ident)
once get_parent_ident promises to always return a valid string. Or
alternatively:

  parent_ident = get_parent_ident();
  if (!parent_ident || strcmp(parent_ident, committer_ident))


A few other comments (I like the idea overall):

  - I haven't looked at the code organization, so maybe it is not
    feasible, but it seems like this stuff should go into wt-status's
    implementation, which would show up in a git-status.

  - The output looks very cluttered. It would be nice to have

    # enter your commit message...
    #
    # Author: whatever
    # Committer: whatever
    #
    # other stuff

    IOW, put in a blank line on either side, but not between the two
    identities if both are shown.
