unstable-list: add the basic about orphan changesets

The goal of this part is to quickly explain orphan and main idea behind its
resolution.

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
=====

#testcases abortcommand abortflag
  $ 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

#if abortflag
  $ cat >> $HGRCPATH <<EOF
  > [alias]
  > abort = evolve --abort
  > EOF
#endif

Testing --abort when no evolve is interrupted
=============================================

#if abortflag
  $ hg evolve --abort
  abort: no interrupted evolve to abort
  [255]
#else
  $ hg abort
  abort: no operation in progress
  [255]
#endif

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"
  [255]

  $ hg evolve --abort --any
  abort: cannot specify both "--any" and "--abort"
  [255]

  $ hg evolve --abort --all
  abort: cannot specify both "--all" and "--abort"
  [255]
