Update to 0.28:

        0.28 release. Cherrypicking, a new testsuite, and some fixes
        and enhancements.

        New features:

        - Cherrypicking with the new "pluck" command. This takes (a \ 
restricted
          subset of) the changes in a revision, or between two
          revisions, and applies them to your workspace.  That this
          has happened is not recorded in history; it as if you
          happened to make some very similar changes by hand in your
          workspace.
        - New automate commands, "automate tags" and "automate \ 
branches".
        - "diff" now knows how to find enclosing function (or
          whatever) bodies, just like GNU diff's "-p" option.
          -- The regex that defines "enclosing function" can be chosen
             on a per-file basis by a hook function; the default hook
             knows about LaTeX, Texinfo, and most programming
             languages.
          -- This is enabled by default; use --no-show-encloser to
             disable.

        Enhancements:

        - When netsync fails due to permission errors, the server returns a
          semi-intelligible message before dropping the connection.
        - When merging a branch with 3 or more heads, the order in which to
          merge the heads will now automatically be chosen to minimize
          the amount of repeated work that must be done.
        - Crash dumps are now written to $CONFDIR/dump when no workspace is
          available
        - Path validation routines are faster.
        - Inodeprints should be slightly more robust now.
        - New hook get_mtn_command, used to determine the path to the
          mtn binary on a remote host, when using ssh support.
        - "diff" now accepts "-u" and "-c" as \ 
short for "--unified"
          (the default) and "--context", respectively.

        Bug fixes:

        - "revert --missing" now works when run in a subdirectory.
        - "revert --missing" now works without any additional files
          being specified.  (You don't have to say "mtn revert
          --missing .".)
        - Fix an edge case where monotone would crash if there was a
          content conflict in a merge for which there was no lca.
        - Fix a case where netsync would sometimes hang during refinement.
        - "mtn help" and "mtn --help" now exit with return \ 
code 0.

        Build environment:

        - automake 1.9 is now required.
        - The testsuite has been rewritten, and should be much faster now. It
          also no longer relies on the presence of a *nix userland.
        - Add workaround for gcc 4.1.[01] bug causing "multiple
          definition" errors.

        Internal:

        - Restrictions have been split into path_restrictions and
          node_restrictions, and generally cleaned up more.
