  * Many 'linkgit:<git documentation page>' references were broken,
    which are all fixed with this.
 
+ * "git describe --contains" often made a hard-to-justify choice of
+   tag to give name to a given commit, because it tried to come up
+   with a name with smallest number of hops from a tag, causing an old
+   commit whose close descendant that is recently tagged were not
+   described with respect to an old tag but with a newer tag.  It did
+   not help that its computation of "hop" count was further tweaked to
+   penalize being on a side branch of a merge.  The logic has been
+   updated to favor using the tag with the oldest tagger date, which
+   is a lot easier to explain to the end users: "We describe a commit
+   in terms of the (chronologically) oldest tag that contains the
+   commit."
+
+ * Running tests with '-x' option to trace the individual command
+   executions is a useful way to debug test scripts, but some tests
+   that capture the standard error stream and check what the command
+   said can be broken with the trace output mixed in.  When running
+   our tests under "bash", however, we can redirect the trace output
+   to another file descriptor to keep the standard error of programs
+   being tested intact.
+
+ * "http.cookieFile" configuration variable clearly wants a pathname,
+   but we forgot to treat it as such by e.g. applying tilde expansion.
+
+ * When de-initialising all submodules, "git submodule deinit" gave a
+   faulty recommendation to use "git submodule deinit .", which would
+   result in a strange error message in a pathological corner case.
+   This has been corrected to suggest "submodule deinit --all" instead.
