Tests for the --abort flag for `hg evolve` command while content-divergence resolution

======================================================================================

The `--abort` flag aborts the interuppted evolve by undoing all the work which

was done during resolution i.e. stripping new changesets created, moving

bookmarks back, moving working directory back.

This test contains cases when `hg evolve` is doing content-divergence resolution.

Setup

=====

  $ cat >> $HGRCPATH <<EOF

  > [phases]

  > publish = False

  > [alias]

  > glog = log -GT "{rev}:{node|short} {desc}\n ({bookmarks}) {phase}"

  > [extensions]

  > EOF

  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

  $ hg init abortrepo

  $ cd abortrepo

  $ echo ".*\.orig" > .hgignore

  $ hg add .hgignore

  $ hg ci -m "added hgignore"

  $ for ch in a b c d; do echo foo > $ch; hg add $ch; hg ci -qm "added "$ch; done;

  $ hg glog
