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

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

The `--abort` flag aborts the interrupted 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 orphan 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

  $ cat >> $HGRCPATH <<EOF

  > [alias]

  > abort = evolve --abort

  > EOF

  $ 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

Testing --abort when no evolve is interrupted

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

  $ hg evolve --abort

  abort: no interrupted evolve to abort

  [255]

Testing with wrong combination of flags

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

  $ hg evolve --abort --continue

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

  [255]

  $ hg evolve --abort --stop

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

  [255]

  $ hg evolve --abort --rev 3

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

  $ hg evolve --abort --any

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

  [255]

  $ hg evolve --abort --all

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

  [255]
