The documentation for the ALLOC_GROW API implicitly encouraged
developers to use "ary" as the variable name for the array which is
dynamically grown. However "ary" is an unusual abbreviation hardly
used anywhere else in the source tree, and it is also better to name
variables based on their contents not on their type.

We record the uncompressed and compressed sizes and the CRC of streamed
files as zero in the local header of the file. The actual values are
recorded in an extra data descriptor after the file content, and in the
usual ZIP directory entry at the end of the archive.
While we know the compressed size and the CRC only after we processed
the contents, we actually know the uncompressed size right from the
start. And for files that we store uncompressed we also already know
their final size.
Do it like InfoZIP's zip and recored the known values, even though they
can be reconstructed using the ZIP directory and the data descriptors
alone. InfoZIP's unzip worked fine before, but NetBSD's version
actually depends on these fields.
The uncompressed size is already set by sha1_object_info(). We just
need to initialize the compressed size to zero or the uncompressed size
depending on the compression method (0 means storing). The CRC was
propertly initialized already.

When a sub-command dies due to a signal, we encode the
signal number into the numeric exit status as "signal -
128". This is easy to identify (versus a regular positive
error code), and when cast to an unsigned integer (e.g., by
feeding it to exit), matches what a POSIX shell would return
when reporting a signal death in $? or through its own exit
code.
So we have a negative value inside the code, but once it
passes across an exit() barrier, it looks positive (and any
code we receive from a sub-shell will have the positive
form). E.g., death by SIGPIPE (signal 13) will look like
-115 to us in inside git, but will end up as 141 when we
call exit() with it. And a program killed by SIGPIPE but run
via the shell will come to us with an exit code of 141.
Unfortunately, this means that when the "use_shell" option
is set, we need to be on the lookout for _both_ forms. We
might or might not have actually invoked the shell (because
we optimize out some useless shell calls). If we didn't invoke
the shell, we will will see the sub-process's signal death
directly, and run-command converts it into a negative value.
But if we did invoke the shell, we will see the shell's
128+signal exit status. To be thorough, we would need to
check both, or cast the value to an unsigned char (after
checking that it is not -1, which is a magic error value).
Fortunately, most callsites do not care at all whether the
exit was from a code or from a signal; they merely check for
a non-zero status, and sometimes propagate the error via
exit(). But for the callers that do care, we can make life
slightly easier by just using the consistent positive form.
This actually fixes two minor bugs:
1. In launch_editor, we check whether the editor died from
SIGINT or SIGQUIT. But we checked only the negative
form, meaning that we would fail to notice a signal
death exit code which was propagated through the shell.
2. In handle_alias, we assume that a negative return value
from run_command means that errno tells us something
interesting (like a fork failure, or ENOENT).
Otherwise, we simply propagate the exit code. Negative
signal death codes confuse us, and we print a useless
"unable to run alias 'foo': Success" message. By
encoding signal deaths using the positive form, the
existing code just propagates it as it would a normal
non-zero exit code.
The downside is that callers of run_command can no longer
differentiate between a signal received directly by the
sub-process, and one propagated. However, no caller
currently cares, and since we already optimize out some
calls to the shell under the hood, that distinction is not
something that should be relied upon by callers.
Fix the same logic in t/test-terminal.perl for consistency [jc:
raised by Jonathan in the discussion].

The name field of a tar header has a size of 100 characters. This limit
was extended long ago in a backward compatible way by providing the
additional prefix field, which can hold 155 additional characters. The
actual path is constructed at extraction time by concatenating the prefix
field, a slash and the name field.
get_path_prefix() is used to determine which slash in the path is used as
the cutting point and thus which part of it is placed into the field
prefix and which into the field name. It tries to cram as much into the
prefix field as possible. (And only if we can't fit a path into the
provided 255 characters we use a pax extended header to store it.)
If a path is longer than 100 but shorter than 156 characters and ends
with a slash (i.e. is for a directory) then get_path_prefix() puts the
whole path in the prefix field and leaves the name field empty. GNU tar
reconstructs the path without complaint, but the tar included with
NetBSD 6 does not: It reports the header to be invalid.
For compatibility with this version of tar, make sure to never leave the
name field empty. In order to do that, trim the trailing slash from the
part considered as possible prefix, if it exists -- that way the last
path component (or more, but not less) will end up in the name field.

Since b57fb80a7d (init, clone: support --separate-git-dir for .git file)
git clone supports the --separate-git-dir option to create the git dir
outside the work tree. But when that option is used, the git dir won't be
deleted in case the clone fails like it would be without this option. This
makes clone lose its atomicity as in case of a failure a partly set up git
dir is left behind. A real world example where this leads to problems is
when "git submodule update" fails to clone a submodule and later calls to
"git submodule update" stumble over the partially set up git dir and try
to revive the submodule from there, which then fails with a not very user
friendly error message.
Fix that by updating the junk_git_dir variable (used to remember if and
what git dir should be removed in case of failure) to the new value given
with the --seperate-git-dir option. Also add a test for this to t5600 (and
while at it fix the former last test to not cd into a directory to test
for its existence but use "test -d" instead).

The test Makefile knows about a few "lint" checks for common
errors. However, they are not enabled as part of "make test"
by default, which means that many people do not bother
running them. Since they are both quick to run and accurate
(i.e., no false positives), there should be no harm in
turning them on and helping submitters catch errors earlier.
We could just set:
TEST_LINT = test-lint
to enable all tests. But that would be unnecessarily
annoying later on if we add slower or less accurate tests
that should not be part of the default. Instead, we name the
tests individually.

- untracked files in committed yet ignored directories are also

- with --untracked-files=normal, untracked directories that
contains only ignored files are dropped too.
Make the behavior more consistent across all possible use cases:
- "--ignored --untracked-files=normal" doesn't show each specific
files but top directory. It instead shows untracked directories
that only contains ignored files, and ignored tracked directories
with untracked files.
- "--ignored --untracked-files=all" shows all ignored files, either
because it's in an ignored directory (tracked or untracked), or
because the file is explicitly ignored.

When testing aliases in t/t1020-subdirectory.sh use longer names so that
they're less likely to conflict with a git-* command somewhere in the
$PATH.
I have a git-ss command in my path which prevents the 'ss' alias from
being used. This command will always fail for git.git, causing the test
to fail. Even if the command succeeded, that would be a false success
for the test since the alias wasn't actually used. A longer, more
descriptive name will make it much less likely that somebody has a
command in their $PATH which will shadow the alias created for the test.
While here, use a longer name for the 'test' alias as well since that is
also short and meaningful enough to make it not unlikely that somebody
would have a command in their $PATH which will shadow that as well.

In the distant past, the order things were documented was
'Invocation', 'Commands', 'Capabilities', ...
Then it was decided that before giving a list of Commands, there
should be an overall description of the 'Input format', which was
a wise decision. However, this description was put as the very
first thing, with the rationale that any implementor would want
to know that first.
However, it seems an implementor would actually first need to
know how the remote helper will be invoked, so moving
'Invocation' to the front again seems logical. Moreover, we now
