Fixes since v1.8.2
------------------
+ * "git submodule update", when recursed into sub-submodules, did not
+ acccumulate the prefix paths.
+
+ * "git am $maildir/" applied messages in an unexpected order; sort
+ filenames read from the maildir/ in a way that is more likely to
+ sort messages in the order the writing MUA meant to, by sorting
+ numeric segment in numeric order and non-numeric segment in
+ alphabetical order.
+
+ * When export-subst is used, "zip" output recorded incorrect
+ size of the file.
+
+ * Some platforms and users spell UTF-8 differently; retry with the
+ most official "UTF-8" when the system does not understand the
+ user-supplied encoding name that are the common alternative
+ spellings of UTF-8.
+
+ * "git branch" did not bother to check nonsense command line
+ parameters and issue errors in many cases.
+
+ * "git update-index -h" did not do the usual "-h(elp)" thing.
+
+ * perl/Git.pm::cat_blob slurped everything in core only to write it
+ out to a file descriptor, which was not a very smart thing to do.
+
+ * The SSL peer verification done by "git imap-send" did not ask for
+ Server Name Indication (RFC 4366), failing to connect SSL/TLS
+ sites that serve multiple hostnames on a single IP.
+
+ * "git index-pack" had a buffer-overflow while preparing an
+ informational message when the translated version of it was too
+ long.
+
+ * Clarify in the documentation "what" gets pushed to "where" when the
+ command line to "git push" does not say these explicitly.
+
+ * In "git reflog expire", REACHABLE bit was not cleared from the
+ correct objects.
+
* The "--color=<when>" argument to the commands in the diff family
was described poorly.
