When sha1_loose_object_info() finds that a loose object file
cannot be stat(2)ed or mmap(2)ed, it returns -1 to signal an
error to the caller. However, if it found that the loose
object file is corrupt and the object data cannot be used
from it, it stuffs OBJ_BAD into "type" field of the
object_info, but returns zero (i.e., success), which can
confuse callers.
This is due to 052fe5eac (sha1_loose_object_info: make type
lookup optional, 2013-07-12), which switched the return to a
strict success/error, rather than returning the type (but
botched the return).
Callers of regular sha1_object_info() don't notice the
difference, as that function returns the type (which is
OBJ_BAD in this case). However, direct callers of
sha1_object_info_extended() see the function return success,
but without setting any meaningful values in the object_info
struct, leading them to access potentially uninitialized
memory.
The easiest way to see the bug is via "cat-file -s", which
will happily ignore the corruption and report whatever
value happened to be in the "size" variable.

Jan Palus noticed that some here-doc are spelled incorrectly,
resulting the entire remainder of the test snippet being slurped
into the "expect" file as if it were data, e.g. in this sequence
cat >expect <<EOF &&
... expectation ...
EOF
git $cmd_being_tested >actual &&
test_cmp expect actual
the last command of the test is "cat" that sends everything to
'expect' and succeeds.
Fixing these issues in t7004 and t7030 reveals that "git tag -v"
and "git verify-tag" with their --format option do not work as the
test was expecting originally. Instead of showing both valid tags
and tags with incorrect signatures on their output, tags that do not
pass verification are omitted from the output. Another breakage that
is uncovered is that these tests must be restricted to environment
where gpg is available.
Arguably, that is a safer behaviour, and because the format
specifiers like %(tag) do not have a way to show if the signature
verifies correctly, the command with the --format option cannot be
used to get a list of tags annotated with their signature validity
anyway.
For now, let's fix the here-doc syntax, update the expectation to
match the reality, and update the test prerequisite.
Maybe later when we extend the --format language available to "git
tag -v" and "git verify-tag" to include things like "%(gpg:status)",
we may want to change the behaviour so that piping a list of tag
names into
xargs git verify-tag --format='%(gpg:status) %(tag)'
becomes a good way to produce such a list, but that is a separate
topic.

There are three issues with the test:
* The syntax of the here-doc was wrong, such that the entire test was
sucked into the here-doc, which is why the test succeeded.
* The variable $submodulesha1 was not expanded as it was inside a quoted
here text. We do not want to quote EOF marker for this.
* The redirection from the git command to the output file for comparison
was wrong as the -C operator from git doesn't apply to the redirect path.
Also we're interested in stderr of that command.

A caller of tempfile API that uses stdio interface to write to
files may ignore errors while writing, which is detected when
tempfile is closed (with a call to ferror()). By that time, the
original errno that may have told us what went wrong is likely to
be long gone and was overwritten by an irrelevant value.
close_tempfile() now resets errno to EIO to make errno at least
predictable.
