[issue2774] convert should prune useless branch closing revisions

[Patrick Mézard <bugs@mercurial.selenic.com> at mercurial.selenic.com]

New submission from Patrick Mézard <pmezard at gmail.com>:

If a branch closing revision is no longer a children of a target branch
revision, it should be removed as well:


test branch closing revision pruning if branch is pruned

  $ hg init branchpruning
  $ cd branchpruning
  $ hg branch foo
  marked working directory as branch foo
  $ echo a > a
  $ hg ci -Am adda
  adding a
  $ hg ci --close-branch -m closefoo
  $ hg up 0
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg branch default
  marked working directory as branch default
  $ echo b > b
  $ hg ci -Am addb
  adding b
  $ cat > filemap <<EOF
  > include b
  > EOF
  $ cd ..
  $ hg convert --filemap branchpruning/filemap branchpruning branchpruning-hg
  initializing destination branchpruning-hg repository
