+The way "git push $there $what" interprets $what part given on the

 A handful of ancient commands that have long been deprecated are

+ * Two-level configuration variable names in "branch.*" and "remote.*"

+
+ * Fetching 'frotz' branch with "git fetch", while 'frotz/nitfol'
+   remote-tracking branch from an earlier fetch was still there, would
+   error out, primarily because the command was not told that it is
+   allowed to lose any information on our side.  "git fetch --prune"
+   now can be used to remove 'frotz/nitfol' to make room to fetch and
+   store 'frotz' remote-tracking branch.

+ * "diff.orderfile=<file>" configuration variable can be used to

+
+ * "git difftool" shows how many different paths there are in total,
+   and how many of them have been shown so far, to indicate progress.
+
+ * "git push origin master" used to push our 'master' branch to update
+   the 'master' branch at the 'origin' repository.  This has been
+   enhanced to use the same ref mapping "git push origin" would use to
+   determine what ref at the 'origin' to be updated with our 'master'.
+   For example, with this configuration
+
+   [remote "origin"]
+      push = refs/heads/*:refs/review/*
+
+   that would cause "git push origin" to push out our local branches
+   to corresponding refs under refs/review/ hierarchy at 'origin',
+   "git push origin master" would update 'refs/review/master' over
+   there.  Alternatively, if push.default is set to 'upstream' and our
+   'master' is set to integrate with 'topic' from the 'origin' branch,
+   running "git push origin" while on our 'master' would update their
+   'topic' branch, and running "git push origin master" while on any
+   of our branches does the same.
+
  * "gitweb" learned to treat ref hierarchies other than refs/heads as
    if they are additional branch namespaces (e.g. refs/changes/ in
