Since 39ee4c6c2f (branch: record creation of renamed branch
in HEAD's log, 2017-02-20), a rename on the currently
checked out branch will create two entries in the HEAD
reflog: one where the branch goes away (switching to the
null oid), and one where it comes back (switching away from
the null oid).
This confuses the reflog-walk code. When walking backwards,
it first sees the null oid in the "old" field of the second
entry. Thanks to the "root commit" logic added by 71abeb753f
(reflog: continue walking the reflog past root commits,
2016-06-03), we keep looking for the next entry by scanning
the "new" field from the previous entry. But that field is
also null! We need to go just a tiny bit further, and look
at its "old" field. But with the current code, we decide the
reflog has nothing else to show and just give up. To the
user this looks like the reflog was truncated by the rename
operation, when in fact those entries are still there.
This patch does the absolute minimal fix, which is to look
back that one extra level and keep traversing.
The resulting behavior may not be the _best_ thing to do in
the long run (for example, we show both reflog entries each
with the same commit id), but it's a simple way to fix the
problem without risking further regressions.

It seems to be a little-known feature of `grep` (and it certainly came
as a surprise to this here developer who believed to know the Unix tools
pretty well) that multiple patterns can be passed in the same
command-line argument simply by separating them by newlines. Watch, and
learn:
$ printf '1\n2\n3\n' | grep "$(printf '1\n3\n')"
1
3
That behavior also extends to patterns passed via `-e`, and it is not
modified by passing the option `-E` (but trying this with -P issues the
error "grep: the -P option only supports a single pattern").
It seems that there are more old Unix hands who are surprised by this
behavior, as grep invocations of the form
grep "$(git rev-parse A B) C" file
were introduced in a85b377d04 (push: the beginning of "git push
--signed", 2014-09-12), and later faithfully copy-edited in b9459019bb
(push: heed user.signingkey for signed pushes, 2014-10-22).
Please note that the output of `git rev-parse A B` separates the object
IDs via *newlines*, not via spaces, and those newlines are preserved
because the interpolation is enclosed in double quotes.
As a consequence, these tests try to validate that the file contains
either A's object ID, or B's object ID followed by C, or both. Clearly,
however, what the test wanted to see is that there is a line that
contains all of them.
This is clearly unintended, and the grep invocations in question really
match too many lines.
Fix the test by avoiding the newlines in the patterns.

Some email servers (e.g. smtp.163.com) limit the number emails to be
sent per session (connection) and this will lead to a faliure when
sending many messages.
Teach send-email to disconnect after sending a number of messages
(configurable via the --batch-size=<num> option), wait for a few
seconds (configurable via the --relogin-delay=<seconds> option) and
reconnect, to work around such a limit.
Also add two configuration variables to give these options the default.
Note:
We will use this as a band-aid for now, but in the longer term, we
should look at and react to the SMTP error code from the server;

If a user wants to experiment with the version of collision
detecting sha1 from the submodule, the user needed to not just
populate the submodule but also needed to turn the knob.
A Makefile trick is easy enough to do so, so let's do this. When
somebody with a copy of the submodule populated wants not to use it,
that can be done by overriding it in config.mak or from the command
line.

Update sha1dc from the latest version by the upstream maintainer[1].
See commit 6b851e536b ("sha1dc: update from upstream", 2017-06-06) for
the last update.
This solves the Big Endian detection on Solaris reported against
v2.13.2[2], hopefully without any regressions. A version of this has
been tested on two Solaris SPARC installations, Cygwin (by jturney on
cygwin@Freenode), and on numerous more boring systems (mainly
linux/x86_64). See [3] for a discussion of the implementation and
platform-specific issues.
See commit a0103914c2 ("sha1dc: update from upstream", 2017-05-20) and
6b851e536b ("sha1dc: update from upstream", 2017-06-06) for previous
attempts in the 2.13 series to address various compile-time feature

strbuf_addftime() allows callers to pass a time zone name for
expanding %Z. The only current caller either passes the empty string
or NULL, in which case %Z is handed over verbatim to strftime(3).
Replace that string parameter with a flag controlling whether to
remove %Z from the format specification. This simplifies the code.

"git status" has long shown essentially the same message as "git
commit"; the message it gives while preparing for the root commit,
i.e. "Initial commit", was hard to understand for some new users.
Now it says "No commits yet" to stress more on the current status
(rather than the commit the user is preparing for, which is more in
line with the focus of "git commit").
* ks/status-initial-commit:
status: contextually notify user about an initial commit
Traditionally, the default die() routine had a code to prevent it
from getting called multiple times, which interacted badly when a
threaded program used it (one downside is that the real error may
be hidden and instead the only error message given to the user may
end up being "die recursion detected", which is not very useful).

There are two rules for using FREE_AND_NULL in free.cocci, one for
pointer types and one for expressions. Both cause coccinelle to remove
empty lines and even newline characters between replacements for some
reason; consecutive "free(x);/x=NULL;" sequences end up as multiple
FREE_AND_NULL calls on the same time.
Remove the type rule, as the expression rule already covers it, and
rearrange the lines of the latter to place the addition of FREE_AND_NULL
between the removals, which causes coccinelle to leave surrounding
whitespace untouched.

Currently, regardless of the contents of the "struct object_info" passed

Add the ability to pass NULL, and use NULL-ness of the argument to

needlessly access the packfile. A subsequent patch will make use of this
optimization.
