This makes the tests more robust against changing output formats, by
allowing us to centralize fixes in the sanitization function. It is
not appropriate for all cases, in particular it is unneeded when using
test_json_nodes, and unhelpful when testing filenames.
This is based on a patch from Johan Parin [1], which is in turn
responding to a bug report / feature requiest from Jan Malkhovski.
The update to the structured output documented in schemata is intended
to be upward compatible, so the format version stays the same

Sourcing test-lib.sh will cd to TMP_DIRECTORY, so
relative path in $0 will not work in previous version
. $(dirname "$0")/test-lib-emacs.sh
Now individual test scripts -- e.g. ./test/T310-emacs.sh
will work.
I haven't traced the code path as exhaustively for the SMIME test, but
the expiry date in question is larger then representable in a signed
32 bit integer.
In particular, timestamps beyond 2038 could overflow the sprinter
interface on systems where time_t is 64-bit but 'int' is a signed 32-bit
integer type.
This allows MUAs that don't want to think about per-mime-part
cryptographic status to have a simple high-level overview of the
message's cryptographic state.
Sensibly structured encrypted and/or signed messages will work fine
with this. The only requirement for the simplest encryption + signing
is that the message have all of its encryption and signing protection
(the "cryptographic envelope") in a contiguous set of MIME layers at
the very outside of the message itself.
This is because messages with some subparts signed or encrypted, but
with other subparts with no cryptographic protection is very difficult
to reason about, and even harder for the user to make sense of or work
with.
For further characterization of the Cryptographic Envelope and some of
the usability tradeoffs, see here:

The corresponding xapian document just gets more terms added to it,
but this doesn't seem to break anything. Values on the other hand get
overwritten, which is a bit annoying, but arguably it is not worse to
take the values (from, subject, date) from the last file indexed
rather than the first.
Unify the subtests by requiring test_begin_subtest before
test_expect_code. (Similar change for test_expect_success has already
been done.)
This increases clarity in the test scripts by having a separate line
for the start of the subtest with the heading, and makes it possible
to simplify the test infrastructure by making all subtests similar.
Instead of just having the first filename for the message, list all
duplicate filenames of the message as a list in the formatted
outputs. This bumps the format version to 3.
The files (test) scripts source (with builtin command `.`) provides
information which the scripts depend, and without the `source` to
succeed allowing script to continue may lead to dangerous situations
(e.g. rm -rf "${undefined_variable}"/*).
At the end of all source (.) lines construct ' || exit 1' was added;
In our case the script script will exit if it cannot find (or read) the
file to be sourced. Additionally script would also exits if the last
command of the sourced file exited nonzero.
All test scripts to be executed are now named as T\d\d\d-name.sh,
numers in increments of 10.
This eases adding new tests and developers to see which are test scripts
that are executed by test suite and in which order.
