daemon is torn down were flaky. This was fixed by reacting to
ECONNRESET and behaving as if we got an EOF.
+ * Some versions of GnuPG fail to kill gpg-agent it auto-spawned
+ and such a left-over agent can interfere with a test. Work it
+ around by attempting to kill one before starting a new test.
+
+ * "git log --tag=no-such-tag" showed log starting from HEAD, which
+ has been fixed---it now shows nothing.
+
+ * The "tag.pager" configuration variable was useless for those who
+ actually create tag objects, as it interfered with the use of an
+ editor. A new mechanism has been introduced for commands to enable
+ pager depending on what operation is being carried out to fix this,
+ and then "git tag -l" is made to run pager by default.
+
+ * "git push --recurse-submodules $there HEAD:$target" was not
+ propagated down to the submodules, but now it is.
+
+ * Commands like "git rebase" accepted the --rerere-autoupdate option
+ from the command line, but did not always use it. This has been
+ fixed.
+
+ * "git clone --recurse-submodules --quiet" did not pass the quiet
+ option down to submodules.
+
+ * "git am -s" has been taught that some input may end with a trailer
+ block that is not Signed-off-by: and it should refrain from adding
+ an extra blank line before adding a new sign-off in such a case.
+
+ * "git svn" used with "--localtime" option did not compute the tz
+ offset for the timestamp in question and instead always used the
+ current time, which has been corrected.
+
+ * Memory leaks in a few error codepaths have been plugged.
+
+ * bash 4.4 or newer gave a warning on NUL byte in command
+ substitution done in "git stash"; this has been squelched.
+
+ * "git grep -L" and "git grep --quiet -L" reported different exit
+ codes; this has been corrected.
+
+ * When handshake with a subprocess filter notices that the process
+ asked for an unknown capability, Git did not report what program
+ the offending subprocess was running. This has been corrected.
+
+ * "git apply" that is used as a better "patch -p1" failed to apply a
+ taken from a file with CRLF line endings to a file with CRLF line
+ endings. The root cause was because it misused convert_to_git()
+ that tried to do "safe-crlf" processing by looking at the index
+ entry at the same path, which is a nonsense---in that mode, "apply"
+ is not working on the data in (or derived from) the index at all.
+ This has been fixed.
+
+ * Killing "git merge --edit" before the editor returns control left
+ the repository in a state with MERGE_MSG but without MERGE_HEAD,
+ which incorrectly tells the subsequent "git commit" that there was
+ a squash merge in progress. This has been fixed.
+
+ * "git archive" did not work well with pathspecs and the
+ export-ignore attribute.
+
+ * "git cvsserver" no longer is invoked by "git daemon" by default,
+ as it is old and largely unmaintained.
+
+ * Various Perl scripts did not use safe_pipe_capture() instead of
+ backticks, leaving them susceptible to end-user input. They have
+ been corrected.
+
Also contains various documentation updates and code clean-ups.
