rollback: clarifies the message about the reverted state (issue2628)

Previously, when rolling back a transaction, some users could be confused
between the level to which the store is rolled back, and the new parents
of the working directory.

  $ hg rollback
  rolling back to revision 4 (undo commit)

With this change:
  $ hg rollback
  repository tip rolled back to tip revision 4 (undo commit)
  working directory now based on revision 2 and 1

So now the user can realize that the store has been rolled back to an older
tip, but also that the working directory may not on the tip (here we are
rolling back the merge of the heads 2 and 1)

  $ hg help notify
  notify extension - hooks for sending email notifications at commit/push time
  
  Subscriptions can be managed through a hgrc file. Default mode is to print
  messages to stdout, for testing and configuring.
  
  To use, configure the notify extension and enable it in hgrc like this:
  
    [extensions]
    notify =
  
    [hooks]
    # one email for each incoming changeset
    incoming.notify = python:hgext.notify.hook
    # batch emails when many changesets incoming at one time
    changegroup.notify = python:hgext.notify.hook
  
    [notify]
    # config items go here
  
  Required configuration items:
  
    config = /path/to/file # file containing subscriptions
  
  Optional configuration items:
  
    test = True            # print messages to stdout for testing
    strip = 3              # number of slashes to strip for url paths
    domain = example.com   # domain to use if committer missing domain
    style = ...            # style file to use when formatting email
    template = ...         # template to use when formatting email
    incoming = ...         # template to use when run as incoming hook
    changegroup = ...      # template when run as changegroup hook
    maxdiff = 300          # max lines of diffs to include (0=none, -1=all)
    maxsubject = 67        # truncate subject line longer than this
    diffstat = True        # add a diffstat before the diff content
    sources = serve        # notify if source of incoming changes in this list
                           # (serve == ssh or http, push, pull, bundle)
    merge = False          # send notification for merges (default True)
    [email]
    from = [e-mail]   # email address to send as if none given
    [web]
    baseurl = http://hgserver/... # root of hg web site for browsing commits
  
  The notify config file has same format as a regular hgrc file. It has two
  sections so you can express subscriptions in whatever way is handier for you.
  
    [usersubs]
    # key is subscriber email, value is ","-separated list of glob patterns
    user@host = pattern
  
    [reposubs]
    # key is glob pattern, value is ","-separated list of subscriber emails
    pattern = user@host
  
  Glob patterns are matched against path to repository root.
  
  If you like, you can put notify config file in repository that users can push
  changes to, they can manage their own subscriptions.
  
  no commands defined
  $ hg init a
  $ echo a > a/a

commit

  $ hg --cwd a commit -Ama -d '0 0'
  adding a


clone

  $ hg --traceback clone a b
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo a >> a/a

commit

  $ hg --traceback --cwd a commit -Amb -d '1 0'

on Mac OS X 10.5 the tmp path is very long so would get stripped in the subject line

  $ cat <<EOF >> $HGRCPATH
  > [notify]
  > maxsubject = 200
  > EOF

the python call below wraps continuation lines, which appear on Mac OS X 10.5 because
of the very long subject line
pull (minimal config)

  $ hg --traceback --cwd b pull ../a | \
  >   python -c 'import sys,re; print re.sub("\n[\t ]", " ", sys.stdin.read()),'
