The following part of the description:
git bisect (bad|new) [<rev>]
git bisect (good|old) [<rev>...]
may be a bit confusing, as a reader may wonder if instead it should be:
git bisect (bad|good) [<rev>]
git bisect (old|new) [<rev>...]
Of course the difference between "[<rev>]" and "[<rev>...]" should hint
that there is a good reason for the way it is.
But we can further clarify and complete the description by adding
"<term-new>" and "<term-old>" to the "bad|new" and "good|old"
alternatives.

This allows a natural user-interface when looking for any change in the
code, not just regression. For example:
git bisect start --term-old fast --term-new slow
git bisect fast
git bisect slow
...
There were several proposed user-interfaces for this feature. This patch
implements it as options to 'git bisect start' for the following reasons:
* By construction, the terms will be valid for one and only one
bisection.
* Unlike positional arguments, using named options avoid having to
remember an order.
* We can combine user-defined terms and passing old/new commits as
argument to "git bisect start".
* The implementation is relatively simple.

When not looking for a regression during a bisect but for a fix or a
change in another given property, it can be confusing to use 'good'
and 'bad'.
This patch introduce `git bisect new` and `git bisect old` as an
alternative to 'bad' and good': the commits which have a certain
property must be marked as `new` and the ones which do not as `old`.
The output will be the first commit after the change in the property.
During a new/old bisect session you cannot use bad/good commands and
vice-versa.
Some commands are still not available for old/new:
* git rev-list --bisect does not treat the revs/bisect/new and
revs/bisect/old-SHA1 files.

This is currently only a defensive check since the only terms are

As-is, the revisions that appear on the command-line are processed in
order. This would mix badly with code that changes the configuration
(e.g. change $TERM_GOOD and $TERM_BAD) while processing the options.

We create a file BISECT_TERMS in the repository .git to be read during a
bisection. There's no user-interface yet, but "git bisect" works if terms
other than old/new or bad/good are set in .git/BISECT_TERMS. The
fonctions to be changed if we add new terms are quite few.
In git-bisect.sh:

To add new tags like old/new and have keywords less confusing, the
first step is to avoid hardcoding the keywords.
The default mode is still bad/good.

Thoroughly revise the "git bisect" manpage, including:
* Beef up the "Description" section.
* Make the first long example less specific to kernel development.
* De-emphasize implementation details in a couple of places.
* Add "(roughly N steps)" in the places where example output is shown.
* Properly markup code within the prose.
* Lots of wordsmithing.

Code clean-up.
* rs/janitorial:
dir: remove unused variable sb
clean: remove unused variable buf
use file_exists() to check if a file exists in the worktree
"git clean pathspec..." tried to lstat(2) and complain even for
paths outside the given pathspec.
* dt/clean-pathspec-filter-then-lstat:

Communication between the HTTP server and http_backend process can
lead to a dead-lock when relaying a large ref negotiation request.
Diagnose the situation better, and mitigate it by reading such a
request first into core (to a reasonable limit).
* jk/http-backend-deadlock:
http-backend: spool ref negotiation requests to buffer
t5551: factor out tag creation
http-backend: fix die recursion with custom handler
The clean/smudge interface did not work well when filtering an
empty contents (failed and then passed the empty input through).
It can be argued that a filter that produces anything but empty for
an empty input is nonsense, but if the user wants to do strange
things, then why not?
* jh/filter-empty-contents:
sha1_file: pass empty buffer to index empty file
Make "git stash something --help" error out, so that users can
safely say "git stash drop --help".
* jk/stash-options:
stash: recognize "--help" for subcommands
stash: complain about unknown flags
Clarify that "log --raw" and "log --format=raw" are unrelated
concepts.
* mm/log-format-raw-doc:
Documentation/log: clarify sha1 non-abbreviation in log --raw
Documentation/log: clarify what --raw means
Catch a programmer mistake to feed a pointer not an array to
ARRAY_SIZE() macro, by using a couple of GCC extensions.
* ep/do-not-feed-a-pointer-to-array-size:
git-compat-util.h: implement a different ARRAY_SIZE macro for for safely deriving the size of array
An earlier optimization broke index-pack for a large object
transfer; this fixes it before the breakage hits any released
version.
* nd/slim-index-pack-memory-usage:
index-pack: fix truncation of off_t in comparison
The setup code used to die when core.bare and core.worktree are set
inconsistently, even for commands that do not need working tree.
* jk/die-on-bogus-worktree-late:
setup_git_directory: delay core.bare/core.worktree errors
"git send-email" learned the alias file format used by the sendmail
program (in an abbreviated form).
* ah/send-email-sendmail-alias:
t9001: write $HOME/, not ~/, to help shells without tilde expansion
send-email: add sendmail email aliases format

"git revert" takes.
* tb/complete-sequencing:
completion: suggest sequencer commands for revert
Recent "git prune" traverses young unreachable objects to safekeep
old objects in the reachability chain from them, which sometimes
caused error messages that are unnecessarily alarming.
* jk/squelch-missing-link-warning-for-unreachable:
suppress errors on missing UNINTERESTING links
silence broken link warnings with revs->ignore_missing_links

t5520: check reflog action in fast-forward merge
t5521: test --dry-run does not make any changes
t5520: test --rebase failure on unborn branch with index
t5520: test --rebase with multiple branches
t5520: test work tree fast-forward when fetch updates head
t5520: test for failure if index has unresolved entries
t5520: test no merge candidates cases
t5520: prevent field splitting in content comparisons
The configuration reader/writer uses mmap(2) interface to access
the files; when we find a directory, it barfed with "Out of memory?".
* jk/diagnose-config-mmap-failure:
xmmap(): drop "Out of memory?"
config.c: rewrite ENODEV into EISDIR when mmap fails
config.c: avoid xmmap error messages
config.c: fix mmap leak when writing config
read-cache.c: drop PROT_WRITE from mmap of index

* mh/verify-lock-error-report:
ref_transaction_commit(): do not capitalize error messages
verify_lock(): do not capitalize error messages
verify_lock(): report errors via a strbuf
verify_lock(): on errors, let the caller unlock the lock
verify_lock(): return 0/-1 rather than struct ref_lock *
"color.diff.plain" was a misnomer; give it 'color.diff.context' as
