[PATCH 0/3] prepare for a rev/range that begins with a dash

It turns out that telling handle_revision_opt() not to molest argv[left++] does not have heavy fallout.

Junio C Hamano (3):
  handle_revision_opt(): do not update argv[left++] with an unknown arg
  setup_revisions(): swap if/else bodies to make the next step more readable
  setup_revisions(): allow a rev that begins with a dash
