Log Message:
Update to version 0.38.  Fix one line of post-install target to allow
for DESTDIR support.  Also, patch-ab is no longer necessary; patch-aa
is merely a one-liner now.

Changes since 0.37:

        Changes

        - mtn log now prints a single dot for a project's root
          directory instead of an empty string.

        - mtn now warns if changes to a file will be ignored because
          the file has been deleted on one side of a merge.

        - mtn now errors if your chosen private key doesn't match the public
          key of the same name in your database.

        - mtn now checks for your key before a merge action takes place to
          ensure that any manually merged file isn't lost in an error case

        Bugs fixed

        - a bug introduced in 0.37 prevented an external merger from being
          executed unless the MTN_MERGE environment variable was set

        - mtn read successfully reads revision data, and cert packets again

        - mtn consistently supports certs with empty values
          (fixed 'ls certs' and 'read')

        Internal

        - Update Botan to 1.7.2.

        - Moved the gzip implementation out of the Botan directory.

	Other

        - Added the scripts of the following Lua-based contributed
          Monotone extension commands to contrib/command/:
          "mtn base", "mtn fuse", "mtn revision", \ 
"mtn conflicts".

        - Added a hooks version of the contributed ciabot script,
          contrib/ciabot_monotone_hookversion.lua

	- The monotone manual is now licensed under the GPL rather than
	  the GFDL.
