By the looks of it, this installs five commands whose names start with 'del':

  git-delete-branch
  git-delete-merged-branches
  git-delete-submodule
  git-delete-tag
  git-delta

If this is indeed the case, then ...

... this behavior would, in fact, be a bug, because 'del' is the unique prefix of those five commands.
