REVISION SUMMARY
  With D9255 <https://phab.mercurial-scm.org/D9255>, I made it so `hg split` respects the
  `commmand-templates.oneline-summary` config. I don't think I realized
  that the output I modified was being put in a commit message
  template. The result was that if you have coloring enabled, you get
  colors in the commit template. This patch show that. The test is
  unfortunately pretty verbose (like most other `hg split` tests) and
  shows a bunch of irrelevant "color codes" (templater labels).
