This allows to cancel the current merge without resetting worktree/index,
which is what --abort is for. Like other --quit(s), this is often used
when you forgot that you're in the middle of a merge and already
switched away, doing different things. By the time you've realized, you
can't even continue the merge anymore.
This also makes all in-progress commands, am, merge, rebase, revert and
cherry-pick, take all three --abort, --continue and --quit (bisect has a
different UI).

I fixed a bug that had broken the reading of sendmail.transferEncoding
in 3494dfd3ee ("send-email: do defaults -> config -> getopt in that
order", 2019-05-09), but the test I added in that commit did nothing
to assert the bug had been fixed.
That issue originates in 8d81408435 ("git-send-email: add
--transfer-encoding option", 2014-11-25) which first added the
"sendemail.transferencoding=8bit".
That test has never done anything meaningful. It tested that the
"--transfer-encoding=8bit" option would turn on the 8bit
Transfer-Encoding, but that was the default at the time (and now). As
checking out 8d81408435 and editing the test to remove that option
will reveal, supplying it never did anything.
So when I copied it thinking it would work in 3494dfd3ee I copied a
previously broken test, although I was making sure it did the right
thing via da-hoc debugger inspection, so the bug was fixed.
So fix the test I added in 3494dfd3ee, as well as the long-standing
test added in 8d81408435. To test if we're actually setting the
Transfer-Encoding let's set it to 7bit, not 8bit, as 7bit will error
out on "email-using-8bit".
This means that we can remove the "sendemail.transferencoding=7bit
fails on 8bit data" test, since it was redundant, we now have other
tests that assert that that'll fail.
While I'm at it convert "git config <key> <value>" in the test setup
to just "-c <key>=<value>" on the command-line. Then we don't need to
cleanup after these tests, and there's no sense in asserting where
config values come from in these tests, we can take that as a given.

Change test code added in f434c083a0 ("send-email: add --no-cc,

"$patches" variable was supplied more than once.
As it turns out we didn't need more than one "$patches" for the test

Change our default CC_LD_DYNPATH invocation to something GCC likes
these days. Since the GCC 4.6 release unknown flags haven't been
passed through to ld(1). Thus our previous default of CC_LD_DYNPATH=-R
would cause an error on modern GCC unless NO_R_TO_GCC_LINKER was set.
This CC_LD_DYNPATH flag is really obscure, and I don't expect anyone
except those working on git development ever use this.
It's not needed to simply link to libraries like say libpcre,
but *only* for those cases where we're linking to such a library not
present in the OS's library directories. See e.g. ldconfig(8) on Linux
for more details.
I use this to compile my git with a LIBPCREDIR=$HOME/g/pcre2/inst as
I'm building that from source, but someone maintaining an OS package
is almost certainly not going to use this. They're just going to set
USE_LIBPCRE=YesPlease after installing the libpcre dependency,
which'll point to OS libraries which ld(1) will find without the help
of CC_LD_DYNPATH.
Another thing that helps mitigate any potential breakage is that we
detect the right type of invocation in configure.ac, which e.g. HP/UX
uses[1], as does IBM's AIX package[2]. From what I can tell both AIX
and Solaris packagers are building git with GCC, so I'm not adding a
corresponding config.mak.uname default to cater to their OS-native
linkers.
Now for an overview of past development in this area:
Our use of "-R" dates back to 455a7f3275 ("More portability.",
2005-09-30). Soon after that in bbfc63dd78 ("gcc does not necessarily
pass runtime libpath with -R", 2006-12-27) the NO_R_TO_GCC flag was
added, allowing optional use of "-Wl,-rpath=".
Then in f5b904db6b ("Makefile: Allow CC_LD_DYNPATH to be overriden",
2008-08-16) the ability to override this flag to something else
entirely was added, as some linkers use neither "-Wl,-rpath," nor
"-R".
From what I can tell we should, with the benefit of hindsight, have
made this change back in 2006. GCC & ld supported this type of
invocation back then, or since at least binutils-gdb.git's[3]
a1ad915dc4 ("[...]Add support for -rpath[...]", 1994-07-20).
Further reading and prior art can be found at [4][5][6][7]. Making a
plain "-R" an error seems from reading those reports to have been
introduced in GCC 4.6 released on March 25, 2011[8], but I couldn't
confirm this with absolute certainty, its release notes are ambiguous
on the subject, and I couldn't be bothered to try to build & bisect it
against GCC 4.5.

In git-format-patch, notes can be appended with the `--notes` option.
However, this must be specified by the user on an
invocation-by-invocation basis. If a user is not careful, it's possible
that they may forget to include it and generate a patch series without
notes.
Teach git-format-patch the `format.notes` config option. Its value is a
notes ref that will be automatically appended. The special value of
"standard" can be used to specify the standard notes. This option is
overridable with the `--no-notes` option in case a user wishes not to
append notes.

When a remote helper exposes the "import" capability, stdout of the
helper is sent to stdin of a new fast-import process. This is done by
setting the corresponding child_process's in field to the value of the
out field of the helper child_process.
The child_process API is defined to close the file descriptors it's
given when calling start_command. This means when start_command is
called for the fast-import process, its input fd (the output fd of the
helper), is closed.
But when the transport helper is later destroyed, in disconnect_helper,
its input and output are closed, which means close() is called with
an invalid fd (since it was already closed as per above). Or worse, with
a valid fd owned by something else (since fd numbers can be reused).

The function's definition has a paramter of type "int" qualified as
"const". The fact that the incoming parameter is used as read-only
in the fuction is an implementation detail that the callers should
not have to be told in the prototype declaring it (and "const" there
has no effect, as C passes parameters by value).
The prototype defined for the function in pkt-line.h lacked the
matching "const" for this reason, but apparently some compilers
(e.g. MS Visual C 2017) complain about the parameter type mismatch.
Let's squelch it by removing the "const" that is pointless in the
definition of a small and trivial function like this, which would
not help optimizing compilers nor reading humans that much.

The JGIT prereq uses `type jgit` to determine whether jgit is present.
While this is usually sufficient, it won't help if the jgit found is
badly broken. This wastes time running tests which fail due to no fault
of our own.
Use `jgit --version` instead, to guard against cases where jgit is
present on the system, but will fail to run, e.g. because of some JRE
issue, or missing Java dependencies. Checking that it gets far enough
to process the '--version' argument isn't perfect, but seems to be good
enough in practice. It's also consistent with how we detect some other
dependencies, see e.g. the CURL and UNZIP prerequisites.
