* A handful of "git svn" updates.
+ * "git push" learned to accept and pass extra options to the
+ receiving end so that hooks can read and react to them.
+
+ * "git status" learned to suggest "merge --abort" during a conflicted
+ merge, just like it already suggests "rebase --abort" during a
+ conflicted rebase.
+ (merge b0a61ab mm/status-suggest-merge-abort later to maint).
+
+ * "git jump" script (in contrib/) has been updated a bit.
+ (merge a91e692 jk/git-jump later to maint).
+
+ * "git push" and "git clone" learned to give better progress meters
+ to the end user who is waiting on the terminal.
+
Performance, Internal Implementation, Development Support etc.
* A few tests that specifically target "git rebase -i" have been
added.
+ * Dumb http transport on the client side has been optimized.
+ (merge ecba195 ew/http-walker later to maint).
+
+ * Users of the parse_options_concat() API function need to allocate
+ extra slots in advance and fill them with OPT_END() when they want
+ to decide the set of supported options dynamically, which makes the
+ code error-prone and hard to read. This has been corrected by tweaking
+ the API to allocate and return a new copy of "struct option" array.
+ (merge 023ff39 jk/parse-options-concat later to maint).
+
+ * "git fetch" exchanges batched have/ack messages between the sender
+ and the receiver, initially doubling every time and then falling
+ back to enlarge the window size linearly. The "smart http"
+ transport, being an half-duplex protocol, outgrows the preset limit
+ too quickly and becomes inefficient when interacting with a large
+ repository. The internal mechanism learned to grow the window size
+ more aggressively when working with the "smart http" transport.

Also contains various documentation updates and code clean-ups.

(merge 259f22a ew/find-perl-on-freebsd-in-local later to maint).
+ * "git commit --help" said "--no-verify" is only about skipping the
+ pre-commit hook, and failed to say that it also skipped the
+ commit-msg hook.
+ (merge def480f os/no-verify-skips-commit-msg-too later to maint).
+
+ * "git merge" in Git v2.9 was taught to forbid merging an unrelated
+ lines of history by default, but that is exactly the kind of thing
+ the "--rejoin" mode of "git subtree" (in contrib/) wants to do.
+ "git subtree" has been taught to use the "--allow-unrelated-histories"
+ option to override the default.
+ (merge 0f12c7d da/subtree-2.9-regression later to maint).
+
+ * The build procedure for "git persistent-https" helper (in contrib/)
+ has been updated so that it can be built with more recent versions
+ of Go.
+ (merge accb613 pm/build-persistent-https-with-recent-go later to maint).
+
+ * There is an optimization used in "git diff $treeA $treeB" to borrow
+ an already checked-out copy in the working tree when it is known to
+ be the same as the blob being compared, expecting that open/mmap of
+ such a file is faster than reading it from the object store, which
+ involves inflating and applying delta. This however kicked in even
+ when the checked-out copy needs to go through the convert-to-git
+ conversion (including the clean filter), which defeats the whole
+ point of the optimization. The optimization has been disabled when
+ the conversion is necessary.
+ (merge 06dec43 jk/diff-do-not-reuse-wtf-needs-cleaning later to maint).
+
+ * "git -c grep.patternType=extended log --basic-regexp" misbehaved
+ because the internal API to access the grep machinery was not
+ designed well.
+ (merge 8465541 jc/grep-commandline-vs-configuration later to maint).
