hashcpy with null_sha1 as the source is equivalent to hashclr. In
addition to being simpler, using hashclr may give the compiler a chance
to optimize better. Convert instances of hashcpy with the source
argument of null_sha1 to hashclr.
This transformation was implemented using the following semantic patch:
@@
expression E1;
@@
-hashcpy(E1, null_sha1);
+hashclr(E1);

When we run scripted Porcelains, "git" potty has set up the $PATH by
prepending $GIT_EXEC_PATH, the path given by "git --exec-path=$there
$cmd", etc. already. Because of this, scripted Porcelains can
dot-source shell script library like git-sh-setup with simple dot
without specifying any path.
t2300 however dot-sources git-sh-setup without adjusting $PATH like
the real "git" potty does. This has not been a problem so far, but
once git-sh-setup wants to rely on the $PATH adjustment, just like
any scripted Porcelains already do, it would become one. It cannot
for example dot-source another shell library without specifying the
full path to it by prefixing $(git --exec-path).

In t5500::check_prot_host_port_path(), diagport is not a variable
used elsewhere and the function is not recursively called so this
can simply lose the "local", which may not be supported by shell
(besides, the function liberally clobbers other variables without
making them "local").
t7403::reset_submodule_urls() overrides the "root" variable used
in the test framework for no good reason; its use is not about
temporarily relocating where the test repositories are created.
This assignment can be made not to clobber the variable by moving
them into the subshells it already uses. Its value is always
$TRASH_DIRECTORY, so we could use it instead there, and this
function that is called only once and its two subshells may not be
necessary (instead, the caller can use "git -C $there config" and
set a value that is derived from $TRASH_DIRECTORY), but this is a
minimum fix that is needed to lose "local".

The one-shot environment variable syntax:
FOO=BAR some-program
is unportable when some-program is actually a shell
function, like test_must_fail (on some shells FOO remains
set after the function returns, and on others it does not).
We sometimes get around this by using env, like:
test_must_fail env FOO=BAR some-program
But that only works because test_must_fail's arguments are
themselves a command which can be run. You can't run:
env FOO=BAR test_must_fail some-program
because env does not know about our shell functions. So
there is no equivalent for test_commit, for example, and one
must resort to:
(
FOO=BAR
export FOO
test_commit
)
which is a bit verbose. Let's add a version of "env" that
works _inside_ the shell, by creating a subshell, exporting
variables from its argument list, and running the command.
Its use is demonstrated on a currently-unportable case in
t4014.

Running tests with '-x' option to trace the individual command
executions is a useful way to debug test scripts, but some tests
that capture the standard error stream and check what the command
said can be broken with the trace output mixed in. When running
our tests under "bash", however, we can redirect the trace output
to another file descriptor to keep the standard error of programs
being tested intact.

"git describe --contains" often made a hard-to-justify choice of
tag to give name to a given commit, because it tried to come up
with a name with smallest number of hops from a tag, causing an old
commit whose close descendant that is recently tagged were not
described with respect to an old tag but with a newer tag. It did
not help that its computation of "hop" count was further tweaked to
penalize being on a side branch of a merge. The logic has been
updated to favor using the tag with the oldest tagger date, which
is a lot easier to explain to the end users: "We describe a commit
in terms of the (chronologically) oldest tag that contains the
commit."

test_patch_id_file_order shell function uses $name variable to hold
one filename, and calls another shell function calc_patch_id as a
downstream of one pipeline. The called function, however, also uses
the same $name variable. With a shell implementation that runs the
callee in the current shell environment, the caller's $name would
be clobbered by the callee's use of the same variable.
This hasn't been an issue with dash and bash. ksh93 reveals the
breakage in the test script.
Fix it by using a distinct variable name in the callee.

In t0008, we have
cat <<-EOF
...
a/b/.gitignore:8:!on* "a/b/one\"three"
...
EOF
and expect that the backslash-dq is passed through literally.
ksh88 eats the backslash and produces a wrong expect file to
compare the actual output with.
Using \\" works this around without breaking other POSIX shells
(which collapse backslash-backslash to a single backslash), and
ksh88 does so, too.
It makes it easier to read, too, because the reason why we are
writing backslash there is *not* because we think dq is special and
want to quote it (if that were the case we would have two more
backslashes on that line). It is simply because we want a single
literal backslash there. Since backslash is treated specially in
unquoted here-document, explicitly doubling it to quote it expresses
our intent better than relying on the character that immediately
comes after it (i.e. '"') not being a special character.

Ideally, each test should be responsible for setting up state it needs
rather than relying upon transient global state. Toward this end, teach
test_rev_parse() to accept a "-g <dir>" option to allow callers to
specify the value of the GIT_DIR environment variable explicitly. Take
advantage of this new option to avoid polluting the global scope with
GIT_DIR assignments.
Implementation note: Typically, tests avoid polluting the global state
by wrapping transient environment variable assignments within a
subshell, however, this technique doesn't work here since test_config()
and test_unconfig() need to know GIT_DIR, as well, but neither function
can be used within a subshell. Consequently, GIT_DIR is instead cleared
manually via test_when_finished().

Ideally, each test should be responsible for setting up state it needs
rather than relying upon transient global state. Toward this end, teach
test_rev_parse() to accept a "-b <value>" option to allow callers to set
"core.bare" explicitly or undefine it. Take advantage of this new option
to avoid setting "core.bare" outside of tests.
Under the hood, "-b <value>" invokes "test_config -C <dir>" (or
"test_unconfig -C <dir>"), thus git-config knows explicitly where to
find its configuration file. Consequently, the global GIT_CONFIG
environment variable required by the manual git-config invocations
outside of tests is no longer needed, and is thus dropped.

instruct it explicitly in which directory its tests should be run. Take
advantage of this new option to avoid changing the working directory

Implementation note: test_rev_parse() passes "-C <dir>" along to
git-rev-parse with <dir> properly quoted. The natural and POSIX way to
do so is via ${dir:+-C "$dir"}, however, with some older broken shells,
this expression evaluates incorrectly to a single argument ("-C <dir>")
rather than the expected two (-C and "<dir>"). Work around this problem
with the slightly ungainly expression: ${dir:+-C} ${dir:+"$dir"}

Tests run by test_rev_parse() are nearly identical; each invokes
git-rev-parse with a single option and compares the result against an
expected value. Such duplication makes it onerous to extend the tests
since any change needs to be repeated in each test. Avoid the
duplication by parameterizing the test and driving it via a for-loop.
