Tests for the --stop flag for `hg evolve` command while resolving orphans

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

The `--stop` flag stops the interrupted evolution and delete the state file so

user can do other things and comeback and do evolution later on

This is testing cases when `hg evolve` command is doing orphan resolution.

Setup

=====

  $ cat >> $HGRCPATH <<EOF

  > [alias]

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

  > [extensions]

  > EOF

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

  $ hg init stoprepo

  $ cd stoprepo

  $ 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

Testing `--stop` when no evolve is interrupted

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

  $ hg evolve --stop

  abort: no interrupted evolve to stop

  [255]

Testing with wrong combinations of flags

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

  $ hg evolve --stop --rev 1

  abort: cannot specify both "--rev" and "--stop"

  [255]

  $ hg evolve --stop --continue

  abort: cannot specify both "--stop" and "--continue"

  [255]

  $ hg evolve --stop --all

  abort: cannot specify both "--all" and "--stop"

  [255]

  $ hg evolve --stop --any

  abort: cannot specify both "--any" and "--stop"

  [255]

Testing when only one revision is to evolve

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

  $ hg prev

  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  [3] added c

  $ echo bar > d

  $ hg add d

  $ hg amend

  1 new orphan changesets
