To test for a key that is completely unknown to the keyring we need one
to sign the commit with. This was done by generating a new key and not
add it into the keyring. To avoid the key generation overhead and
problems where GPG did hang in CI during it, switch GNUPGHOME to the
empty $GNUPGHOME_NOT_USED instead, therefore making all used keys unknown
for this single `verify-commit` call.

It is useful to know when a branch first diverged in history
from some integration branch in order to be able to enumerate
the user's local changes. However, these local changes can
include arbitrary merges, so it is necessary to ignore this
merge structure when finding the divergence point.
In order to do this, teach the "rev-list" family to accept
"--exclude-first-parent-only", which restricts the traversal
of excluded commits to only follow first parent links.
-A-----E-F-G--main
\ / /
B-C-D--topic
In this example, the goal is to return the set {B, C, D} which
represents a topic branch that has been merged into main branch.
`git rev-list topic ^main` will end up returning no commits
since excluding main will end up traversing the commits on topic
as well. `git rev-list --exclude-first-parent-only topic ^main`
however will return {B, C, D} as desired.
Add docs for the new flag, and clarify the doc for --first-parent
to indicate that it applies to traversing the set of included
commits only.

The C reimplementation of "add -p" fails to split the last hunk in a
file if hunk ends with an addition or deletion without any post context
line unless it is the last file to be processed.
To determine whether a hunk can be split a counter is incremented each
time a context line follows an insertion or deletion. If at the end of
the hunk the value of this counter is greater than one then the hunk
can be split into that number of smaller hunks. If the last hunk in a
file ends with an insertion or deletion then there is no following
context line and the counter will not be incremented. This case is
already handled at the end of the loop where counter is incremented if
the last hunk ended with an insertion or deletion. Unfortunately there
is no similar check between files (likely because the perl version
only ever parses one diff at a time). Fix this by checking if the last
hunk ended with an insertion or deletion when we see the diff header
of a new file and extend the existing regression test.

Clean up some test constructs in preparation for extending the tests
in the next commit. There are three small changes, I've grouped them
together as they're so small it didn't seem worth creating three
separate commits.
1 - "cat file | sed expression" is better written as
"sed expression file".
2 - Follow our usual practice of redirecting the output of git
commands to a file rather than piping it into another command.
3 - Use test_write_lines rather than 'printf "%s\n"'.

The documentation for the eol attribute states that it is "effectively
setting the text attribute". However, this implies that it forces the
text attribute to always be set, which has not been the case since
6523728499 ("convert: unify the "auto" handling of CRLF", 2016-06-28).
Let's avoid confusing users (and the present author when trying to
describe Git's behavior to others) by clearly documenting in which
cases the "eol" attribute has effect.
Specifically, the attribute always has an effect unless the file is
explicitly set as -text, or the file is set as text=auto and the file is
detected as binary.

Right now, it isn't clear what the behavior is when the eol attribute is
set in .gitattributes but the text attribute is not. Let's add some
tests to document this behavior in our code, which happens to be that
the behavior is as if we set the text attribute implicitly. This will
make sure we don't accidentally change the behavior, which somebody is
probably relying on, and serve as documentation to developers.

or: git cat-file (-e | -p) <object>
or: git cat-file (-t | -s) [--allow-unknown-type] <object>

When merging a signed tag, fmt_merge_msg_sigs() is responsible for
populating the body of the merge message with the names of the signed
tags, their signatures, and the validity of those signatures.
In 02769437e1 (ssh signing: use sigc struct to pass payload,
2021-12-09), check_signature() was taught to pass the object payload via
the sigc struct instead of passing the payload buffer separately.
In effect, 02769437e1 causes buf, and sigc.payload to point at the same
region in memory. This causes a problem for fmt_tag_signature(), which
wants to read from this location, since it is freed beforehand by
signature_check_clear() (which frees it via sigc's `payload` member).
That makes the subsequent use in fmt_tag_signature() a use-after-free.
As a result, merge messages did not contain the body of any signed tags.
Luckily, they tend not to contain garbage, either, since the result of
strstr()-ing the object buffer in fmt_tag_signature() is guarded:
const char *tag_body = strstr(buf, "\n\n");
if (tag_body) {
tag_body += 2;
strbuf_add(tagbuf, tag_body, buf + len - tag_body);
}
Unfortunately, the tests in t6200 did not catch this at the time because
they do not search for the body of signed tags in fmt-merge-msg's
output.
Resolve this by waiting to call signature_check_clear() until after its
contents can be safely discarded. Harden ourselves against any future
regressions in this area by making sure we can find signed tag messages
in the output of fmt-merge-msg, too.
