REVISION SUMMARY
  It looks like this was lost when the code was converted to the
  ui.configoverride() context manager in https://phab.mercurial-scm.org/rHGf255b1811f5e454d8d0add4a1190effc82b301be (rebase: get rid
  of ui.backupconfig, 2017-03-16). (And then the bad example was
  duplicated in https://phab.mercurial-scm.org/rHG228916ca12b54b78faccd5c4abc54cba68606637 (rebase: add concludememorynode(), and call
  it when rebasing in-memory, 2017-12-07).)
