'git submodule--helper update-clone' has logic to retry failed clones
a second time. For this purpose, there is a list of submodules to clone,
and a second list that is filled with the submodules to retry. Within
these lists, the submodules are identified by an index as if both lists
were just appended.
This works nicely except when the second clone attempt fails as well. To
report an error, the identifying index must be adjusted by an offset so
that it can be used as an index into the second list. However, the
calculation uses the logical total length of the lists so that the result
always points one past the end of the second list.
Pick the correct index.

git-submodule--helper is invoked as the upstream of a pipe in several
places. Usually, the failure of a program in this position is not
detected by the shell. For this reason, the code inserts a token in the
output stream when git-submodule--helper fails that is detected
downstream, where the shell script is quit with exit code 1.
There happens to be a bug in git-submodule--helper that leads to a
segmentation fault. The test suite triggers the crash in several places,
all of which are protected by 'test_must_fail'. But due to the inspecific
exit code 1, the crash remains undiagnosed.
Extend the failure protocol such that git-submodule--helper's exit code
is passed downstream (only in the case of failure). This enables the
downstream to use it as its own exit code, and 'test_must_fail' to
identify the segmentation fault as an unexpected failure.
The bug itself is fixed in the next commit.

"git submodule update" that drives many "git clone" could
eventually hit flaky servers/network conditions on one of the
submodules; the command learned to retry the attempt.

submodule update: continue when a clone fails
submodule--helper: initial clone learns retry logic
A careless invocation of "git send-email directory/" after editing
0001-change.patch with an editor often ends up sending both
0001-change.patch and its backup file, 0001-change.patch~, causing
embarrassment and a minor confusion. Detect such an input and
offer to skip the backup files when sending the patches out.
* jc/send-email-skip-backup:
send-email: detect and offer to skip backup files
A bug, which caused "git p4" while running under verbose mode to
report paths that are omitted due to branch prefix incorrectly, has
been fixed; the command said "Ignoring file outside of prefix" for
paths that are _inside_.
* ao/p4-has-branch-prefix-fix:
git-p4: correct hasBranchPrefix verbose output
One among four invocations of readlink(1) in our test suite has
been rewritten so that the test can run on systems without the
command (others are in valgrind test framework and t9802).
* ak/t7800-wo-readlink:
t7800: readlink may not be available
The internal code used to show local timezone offset is not
prepared to handle timestamps beyond year 2100, and gave a
bogus offset value to the caller. Use a more benign looking
+0000 instead and let "git log" going in such a case, instead
of aborting.
* jk/tzoffset-fix:
local_tzoffset: detect errors from tm_to_time_t
t0006: test various date formats
t0006: rename test-date's "show" to "relative"
Some platform-specific code had non-ANSI strict declarations of C
functions that do not take any parameters, which has been
corrected.
* js/mingw-parameter-less-c-functions:
mingw: let the build succeed with DEVELOPER=1
Fix unnecessarily waste in the idiomatic use of ': ${VAR=default}'
to set the default value, without enclosing it in double quotes.
* lc/shell-default-value-noexpand:
sh-setup: enclose setting of ${VAR=default} in double-quotes
Fix an unintended regression in v2.9 that breaks "clone --depth"
that recurses down to submodules by forcing the submodules to also
be cloned shallowly, which many server instances that host upstream
of the submodules are not prepared for.
* sb/clone-shallow-passthru:
clone: do not let --depth imply --shallow-submodules
A new run-command API function pipe_command() is introduced to
sanely feed data to the standard input while capturing data from
the standard output and the standard error of an external process,
which is cumbersome to hand-roll correctly without deadlocking.
The codepath to sign data in a prepared buffer with GPG has been
updated to use this API to read from the status-fd to check for
errors (instead of relying on GPG's exit status).
* jk/gpg-interface-cleanup:
gpg-interface: check gpg signature creation status
sign_buffer: use pipe_command
verify_signed_buffer: use pipe_command
run-command: add pipe_command helper
verify_signed_buffer: use tempfile object
verify_signed_buffer: drop pbuf variable
gpg-interface: use child_process.args
Formats of the various data (and how to validate them) where we use
GPG signature have been documented.
* mg/signature-doc:
Documentation/technical: signed merge tag format
Documentation/technical: signed commit format
Documentation/technical: signed tag format
Documentation/technical: describe signature formats
"log --graph --format=" learned that "%>|(N)" specifies the width
relative to the terminal's left edge, not relative to the area to
draw text that is to the right of the ancestry-graph section. It
also now accepts negative N that means the column limit is relative
to the right border.
* nd/graph-width-padded:
pretty.c: support <direction>|(<negative number>) forms
pretty: pass graph width to pretty formatting for use in '%>|(N)'
"git repack" learned the "--keep-unreachable" option, which sends
loose unreachable objects to a pack instead of leaving them loose.
This helps heuristics based on the number of loose objects
(e.g. "gc --auto").
* jk/repack-keep-unreachable:
repack: extend --keep-unreachable to loose objects
repack: add --keep-unreachable option
repack: document --unpack-unreachable option
Teach format-patch and mailsplit (hence "am") how a line that
happens to begin with "From " in the e-mail message is quoted with
">", so that these lines can be restored to their original shape.
* ew/mboxrd-format-am:
am: support --patch-format=mboxrd
mailsplit: support unescaping mboxrd messages
pretty: support "mboxrd" output format
"upload-pack" allows a custom "git pack-objects" replacement when
responding to "fetch/clone" via the uploadpack.packObjectsHook.
* jk/upload-pack-hook:
upload-pack: provide a hook for running pack-objects
t1308: do not get fooled by symbolic links to the source tree
config: add a notion of "scope"
config: return configset value for current_config_ functions

worktree.c: use is_dot_or_dotdot()
git-worktree.txt: keep subcommand listing in alphabetical order
worktree.c: rewrite mark_current_worktree() to avoid strbuf
completion: support git-worktree
"git bisect" makes an internal call to "git diff-tree" when
bisection finds the culprit, but this call did not initialize the
data structure to pass to the diff-tree API correctly.
* jk/bisect-show-tree:
bisect: always call setup_revisions after init_revisions
A small internal API cleanup.
* lf/sideband-returns-void:
upload-pack.c: make send_client_data() return void
sideband.c: make send_sideband() return void
"git add -i/-p" learned to honor diff.compactionHeuristic
experimental knob, so that the user can work on the same hunk split
as "git diff" output.
* jk/add-i-diff-compact-heuristics:
add--interactive: respect diff.compactionHeuristic
The ownership rule for the piece of memory that hold references to
be fetched in "git fetch" was screwy, which has been cleaned up.
* km/fetch-do-not-free-remote-name:
builtin/fetch.c: don't free remote->name after fetch
HTTPd tests learned to show the server error log to help diagnosing
a failing tests.
* nd/test-lib-httpd-show-error-log-in-verbose:
lib-httpd.sh: print error.log on error
Instead of taking advantage of a struct string_list that is
allocated with all NULs happens to be STRING_LIST_INIT_NODUP kind,
initialize them explicitly as such, to document their behaviour
better.
* jk/string-list-static-init:
use string_list initializer consistently
blame,shortlog: don't make local option variables static
interpret-trailers: don't duplicate option strings
parse_opt_string_list: stop allocating new strings
HTTP transport gained an option to produce more detailed debugging
trace.
* ep/http-curl-trace:
imap-send.c: introduce the GIT_TRACE_CURL enviroment variable
http.c: implement the GIT_TRACE_CURL environment variable
"git cherry-pick A" worked on an unborn branch, but "git
cherry-pick A..B" didn't.

Comments about misbehaving FreeBSD shells have been clarified with
the version number (9.x and before are broken, newer ones are OK).
* em/newer-freebsd-shells-are-fine-with-returns:
rebase: update comment about FreeBSD /bin/sh
"git status" used to say "working directory" when it meant "working
tree".
* lv/status-say-working-tree-not-directory:
Use "working tree" instead of "working directory" for git status
"git update-index --add --chmod=+x file" may be usable as an escape
hatch, but not a friendly thing to force for people who do need to
use it regularly. "git add --chmod=+x file" can be used instead.
* et/add-chmod-x:
add: add --chmod=+x / --chmod=-x options
A codepath that used alloca(3) to place an unbounded amount of data
on the stack has been updated to avoid doing so.
* jk/avoid-unbounded-alloca:
tree-diff: avoid alloca for large allocations
The git-prompt scriptlet (in contrib/) was not friendly with those
who uses "set -u", which has been fixed.
* vs/prompt-avoid-unset-variable:
git-prompt.sh: Don't error on null ${ZSH,BASH}_VERSION, $short_sha
"git reflog" stopped upon seeing an entry that denotes a branch
creation event (aka "unborn"), which made it appear as if the
reflog was truncated.
* sg/reflog-past-root:
reflog: continue walking the reflog past root commits
The documentation tries to consistently spell "GPG"; when
referring to the specific program name, "gpg" is used.
* dn/gpg-doc:
Documentation: GPG capitalization
The documentation set has been updated so that literal commands,
configuration variables and environment variables are consistently
typeset in fixed-width font and bold in manpages.
* tr/doc-tt:
