learned to also peek into $path for presense of corresponding
repositories of submodules and borrow objects from there when able.
+ * The "git diff --submodule={short,log}" mechanism has been enhanced
+ to allow "--submodule=diff" to show the patch between the submodule
+ commits bound to the superproject.

Performance, Internal Implementation, Development Support etc.
further be used to teach git-prompt (in contrib/) to make fewer
calls to git.
+ * Extract a small helper out of the function that reads the authors
+ script file "git am" internally uses.

Also contains various documentation updates and code clean-ups.
* "diff-highlight" script (in contrib/) learned to work better with
"git log -p --graph" output.
(merge 3dbfe2b bh/diff-highlight-graph later to maint).
+
+ * The test framework left the number of tests and success/failure
+ count in the t/test-results directory, keyed by the name of the
+ test script plus the process ID. The latter however turned out not
+ to serve any useful purpose. The process ID part of the filename
+ has been removed.
+ (merge 5c885c1 jk/test-lib-drop-pid-from-results later to maint).
+
+ * Having a submodule whose ".git" repository is somehow corrupt
+ caused a few commands that recurse into submodules loop forever.
+ (merge 10f5c52 jc/submodule-anchor-git-dir later to maint).
+
+ * "git symbolic-ref -d HEAD" happily removes the symbolic ref, but
+ the resulting repository becomes an invalid one. Teach the command
+ to forbid removal of HEAD.
+ (merge 12cfa79 jc/forbid-symbolic-ref-d-HEAD later to maint).
+
+ * A test spawned a short-lived background process, which sometimes
+ prevented the test directory from getting removed at the end of the
+ script on some platforms.

+
+ * Update a few tests that used to use GIT_CURL_VERBOSE to use the
+ newer GIT_TRACE_CURL.
