When a submodule repository uses alternate object store mechanism, some
commands that were started from the superproject did not notice it and
failed with "No such object" errors. The subcommands of "git submodule"
command that recursed into the submodule in a separate process were OK;
only the ones that cheated and peeked directly into the submodule's
repository from the primary process were affected.

When adding the information from a tag, put an empty line between the
message of the tag and the commented-out signature verification
information.
At least for the kernel workflow, I often end up re-formatting the message
that people send me in the tag data. In that situation, putting the tag
message and the tag signature verification back-to-back then means that
normal editor "reflow parapgraph" command will get confused and think that
the signature is a continuation of the last message paragraph.
So I always end up having to first add an empty line, and then go back and
reflow the last paragraph. Let's just do it in git directly.
The extra vertical space also makes the verification visually stand out
more from the user-supplied message, so it looks a bit more readable to me
too, but that may be just an odd personal preference.

From the FILES section of the git-config(1) manual:
$GIT_DIR/config::
Repository specific configuration file. (The filename is
of course relative to the repository root, not the working
directory.)
That's confusing because $GIT_DIR really is relative to the working
directory.
$ GIT_DIR=.git GIT_EDITOR='pwd; echo editing'
$ export GIT_DIR GIT_EDITOR
$ git config --edit --local
/home/jrn/src/git/Documentation
editing .git/config
It turns out that the comment is a remnant from older days when the
heading said ".git/config" (which is indeed relative to the top of the
worktree).
It was only when the heading was changed to refer more precisely to
<git dir>/config (see v1.5.3.2~18, AsciiDoc tweak to avoid leading
dot, 2007-09-14) that the parenthesis stopped making sense. Remove
it.

The old code allowed many references to be efficiently added to a
single directory, because it just appended the references to the
containing directory unsorted without doing any searching (and
therefore without requiring any intermediate sorting). But the old
code was inefficient when a large number of subdirectories were added
to a directory, because the directory always had to be searched to see
if the new subdirectory already existed, and this search required the
directory to be sorted first. The same was repeated for every new
subdirectory, so the time scaled like O(N^2), where N is the number of
subdirectories within a single directory.
In practice, references are often added to the ref_cache in
lexicographic order, for example when reading the packed-refs file.
So build some intelligence into add_entry_to_dir() to optimize for the
case of references and/or subdirectories being added in lexicographic
order: if the existing entries were already sorted, and the new entry
comes after the last existing entry, then adjust ref_dir::sorted to
reflect the fact that the ref_dir is still sorted.

inspired this change.

Import the latest 32-bit implementation of count_masked_bytes() from
Linux (arch/x86/include/asm/word-at-a-time.h). It's shorter and avoids
overflows and negative numbers.
This fixes test failures on 32-bit, where negative partial results had
been shifted right using the "wrong" method (logical shift right instead
of arithmetic short right). The compiler is free to chose the method,
so it was only wrong in the sense that it didn't work as intended by us.

If a commit object has a header line at the end of the
buffer that is missing its newline (or if it appears so
because the content on the header line contains a stray
NUL), then git will segfault.
Interestingly, this case is explicitly handled and we do
correctly scan the final line for the header we are looking
for. But if we don't find it, we will dereference NULL while
trying to look at the next line.
Git will never generate such a commit, but it's good to be
defensive. We could die() in such a case, but since it's
easy enough to handle it gracefully, let's just issue a
warning and continue (so you could still view such a commit
with "git show", though you might be missing headers after
the NUL).

When we parse the name and email from a commit to
pretty-print them, we usually can just put the result
directly into our strbuf result. However, if we are going to
use the mailmap, then we must first copy them into a
NUL-terminated buffer to feed to the mailmap machinery.
We did so by using strlcpy into a static buffer, but we used
it wrong. We fed it the length of the substring we wanted to
copy, but never checked that that length was less than the
size of the destination buffer.
The simplest fix is to just use snprintf to copy the
substring properly while still respecting the destination
buffer's size. It might seem like replacing the static
buffer with a strbuf would help, but we need to feed a
static buffer to the mailmap machinery anyway, so there's
not much benefit to handling arbitrary sizes.
A more ideal solution would be for mailmap to grow an
interface that:
1. Takes a pointer and length combination, instead of
assuming a NUL-terminated string.
2. Returns a pointer to the mailmap's allocated string,
rather than copying it into the buffer.
Then we could avoid the need for an extra buffer entirely.
However, doing this would involve a lot of refactoring of
mailmap and of string_list (which mailmap uses to store the
map itself). For now, let's do the simplest thing to fix the
bug.

When reading patterns from a file, we pass the lines as allocated string
buffers to append_grep_pat() and never free them. That's not a problem
because they are needed until the program ends anyway.
However, now that the function duplicates the pattern string, we can
reuse the strbuf after calling that function. This simplifies the code
a bit and plugs a minor memory leak.

Currently, patterns that contain newline characters don't match anything
when given to git grep. Regular grep(1) interprets patterns as lists of
newline separated search strings instead.
Implement this functionality by creating and inserting extra grep_pat
structures for patterns consisting of multiple lines when appending to
the pattern lists. For simplicity, all pattern strings are duplicated.
The original pattern is truncated in place to make it contain only the
first line.

Commit 875b91b (diff --no-index: use strbuf for temporary pathnames,
2012-04-25) introduced a regression when using diff --no-index with
directories. When iterating through a directory, the switch to strbuf
from heap-allocated char arrays caused paths to form like 'dir/file1',
'dir/file1file2', rather than 'dir/file1', 'dir/file2' as expected.
Avoid this by resetting the paths variables to their original length
before each iteration.
