A more complex case, multiple replacements with a prune:

  $ testtemplate() {

  >   drawdag <<'EOS'
  >   B C D  # D/B = B
  >    \|/
  >     A
  > EOS
  >   hg rebase -q -r $B+$C -d $D -T "$1" 2>/dev/null
  > }

  $ testtemplate 'nodechanges default style:\n{nodechanges}'
  nodechanges default style:
