Log Message:
Update monotone and monotone-server to 0.29:

        0.29 release.  Code cleanups and bug fixes.

        New features:

        - The output of 'mtn status' has been changed significantly; the
          output formerly used by 'mtn status --brief' has become the
          default.  For output similar to the old 'mtn status', see
          'mtn automate get_revision'.

        - It is now significantly easier to control what merger
          monotone uses to resolve conflicts; for instance, to use
          emacs to resolve conflicts, add:
             merge = "emacs"
          to your .monotonerc file.  To override temporarily, you can
          also use the environment variable MTN_MERGE, which takes the
          same strings.  Currently recognized strings are "kdiff3",
          "xxdiff", "opendiff", "tortoisemerge", \ 
"emacs", "vim", and
          "meld".

        - Formerly, monotone's sync-over-ssh support required that an
          absolute path be used, with a URL like:
            ssh://venge.net/home/njs/my-db.mtn
          The following syntaxes are now supported as well:
            ssh://venge.net/~/my-db.mtn
            ssh://venge.net/~njs/my-db.mtn

        Bugs fixed:

        - The bug where monotone would sometimes respond to a control-C
          (or several other signals) by locking up and refusing to exit,
          has been fixed.

        - Monotone now properly respects SIGPIPE.  In particular, this
          means that 'mtn log | less' should now exit promptly when
          'less' is exited.

        - 'mtn log' now flushes its output after each message; this
          makes 'mtn log <FILES>' significantly more usable.

        - 'mtn log <FILES>' formerly listed irrelevant revisions (in
          particular, any revision which contained a delete of any files
          or directories, was always included).  This has been fixed.

        - If, during an update, two files both had conflicts, which,
          when resolved, resulting the two files becoming identical, the
          update would error out.  This has been fixed.

        - If _MTN/log exists and does not end in a newline, we now add a
          newline before using the log message.  This removes a problem
          where the string "MTN:" would end up appended to the last line
          of the log message.

        - We no longer buffer up an arbitrarily large number of pending
          writes in the database.  This improves speed and memory usage
          for 'commit', and fixes the problem where 'cvs_import' would
          run out of memory.

        - Monotone's tree walking code (used by 'ls unknown', 'ls
          missing', and friends) now uses much less memory, especially
          on reiserfs.

        Automate changes:

        - 'mtn automate stdio' now uses a configurable block size,
          controlled by command-line option --automate-stdio-size.  This
          is mostly useful for testing speed/memory trade-offs.

        - 'automate attributes' has a new format, which includes more
          information.

        Code cleanup:

        - We now use boost::program_options to parse command line
          options, rather than popt.  The only user-visible change
          should be that --option="" no longer works as a way to set
          some option to the empty string; use --option "".  (This
          change also removes a lot of orphaned and historically buggy
          code from monotone.)

        Other:

        - zsh completion script significantly revised and updated (see
          contrib/monotone.zsh_completion).
