            Bug ID: 5494
           Summary: resolve --list continues to display results after
                    rebase completes
           Product: Mercurial
           Version: 4.1-rc
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: bug
          Priority: wish
         Component: rebase
          Assignee: bugzilla at mercurial-scm.org
          Reporter: rm at fb.com
                CC: mercurial-devel at mercurial-scm.org

In some circumstances after a rebase, the merge state is not properly removed,
and `hg resolve --list` continues to show files as "resolved" when there should
no longer be a merge state at all.

This inside of a test file reproduces the problem:

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > rebase=
  > EOF
  $ hg init repo
  $ cd repo
  $ echo a >> a
  $ hg commit -qAm base
  $ echo b >> a
  $ hg commit -qm b
  $ hg up .^
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo c >> a
  $ hg commit -qm c
  $ hg rebase -s 1 -d 2 --noninteractive
  rebasing 1:fdaca8533b86 "b"
  merging a
  warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
  unresolved conflicts (see hg resolve, then hg rebase --continue)
  $ echo a > a
  $ echo c >> a
  $ hg resolve --mark a
  (no more unresolved files)
  continue: hg rebase --continue
  $ hg rebase --continue
  rebasing 1:fdaca8533b86 "b"
  note: rebase of 1:fdaca8533b86 created no changes to commit
  saved backup bundle to
$TESTTMP/repo/.hg/strip-backup/fdaca8533b86-7fd70513-backup.hg (glob)
  $ hg resolve --list
  R a
  $ ls .hg/merge

Note that .hg/merge should have been deleted but it wasn't, and that the
user-visible error here is that `hg resolve --list` shows a file when there
should be no merge state at all.
