 * Bugfixes
 
+  - Automated merge conflict handling when changes to symbolic
+    links conflicted were completely broken.  The merge-resolve
+    strategy created a regular file with conflict markers in it
+    in place of the symbolic link.  The default strategy,
+    merge-recursive was even more broken.  It removed the path
+    that was pointed at by the symbolic link.  Both of these
+    problems have been fixed.

   - 'git diff maint master next' did not correctly give combined
     diff across three trees.

 * Documentation updates

 Adds a remote named <name> for the repository at
 <url>.  The command `git fetch <name>` can then be used to create and
 update remote-tracking branches <name>/<branch>.
++
+With `-f` option, `git fetch <name>` is run immediately after
+the remote information is set up.
++
+With `-t <branch>` option, instead of the default glob
+refspec for the remote to track all branches under
+`$GIT_DIR/remotes/<name>/`, a refspec to track only `<branch>`
+is created.  You can give more than one `-t <branch>` to track
+multiple branche without grabbing all branches.
++
+With `-m <master>` option, `$GIT_DIR/remotes/<name>/HEAD` is set
+up to point at remote's `<master>` branch instead of whatever
+branch the `HEAD` at the remote repository actually points at.
