Confirm it fails when rebasing a change that conflicts:
  $ hg rebase -r tip -d . --noconflict
  rebasing in-memory!
  rebasing 3:955ac081fc7c "g" (tip)
  merging c
  hit merge conflicts (in c) and --noconflict passed; exiting
  $ hg st
  M b
  $ cat b
  local change

Confirm rebase without a merge behaves the same:
  $ hg rebase -r tip -d .~1 --noconflict
  rebasing in-memory!
  rebasing 3:955ac081fc7c "g" (tip)
  saved backup bundle to $TESTTMP/repo1/.hg/strip-backup/955ac081fc7c-77e57574-rebase.hg

Confirm the flag fails without IMM:

  $ setconfig rebase.experimental.inmemory=False
  $ hg up -C .
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg st
  $ hg rebase -r tip -d . --noconflict
  abort: --noconflict requires in-memory merge

Confirm that it rebases a three-way merge, but no conflict:
  $ newrepo

  $ hg commit -Aq -m "base"
  $ $TESTDIR/seq.py 1 10 > a
  $ hg commit -q -m "extend to 10"
