  hint: if this is due to a renamed file, you can manually input the renamed path, or re-run the command using --config=experimental.copytrace=on to make hg figure out renamed path automatically (which is very slow, and you will need to be patient)
  use (c)hanged version, leave (d)eleted, or leave (u)nresolved, or input (r)enamed path? u
  unresolved conflicts (see hg resolve, then hg rebase --continue)
