98369a6980 sed: fix hex_subst test after after r363679
r363679 is in-fact the future change referenced by the comment, helpfully
left and forgotten by kevans. Instead of just silently not matching, we
should now be erroring out with vigor.

f9ab72bb47 Read commands from stdin when -f - is passed to sed(1)
This patch teaches sed to interpret a "-" in a special way when given
as an argument to the -f flag.

This behavior is also present in GNU sed.

3a4d70c588 sed: attempt to learn about hex escapes (e.g. \x27)
Somewhat predictably, software often wants to use \x27/\x24 among others so
that they can decline worrying about ugly escaping, if said escaping is even
possible. Right now, this software is using these and getting the wrong
results, as we'll interpret those as x27 and x24 respectively. Some examples
of this, when an exp-run was ran, were science/octopus and misc/vifm.

Go ahead and process these at all times.  We allow either one or two digits,
and the tests account for both.  If extra digits are specified, e.g. \x2727,
then the third and fourth digits are interpreted literally as one might
expect.

8655a965fd Update SYNOPSIS section to be consistent regarding -u, -i, and -I.
Apparently, when the -u, -i and -I options where added to sed(1), it was
forgotten to add them to both lines in the SYNOPSIS section. They were only
added to the second line, although they apply to both.

With the updated SYNOPSIS, it is now allowed (and consistent) to run:

sed -i BAK s/foo/bar/g some_file

6e816d8711 sed: process \r, \n, and \t
This is both reasonable and a common GNUism that a lot of ported software
expects.

Universally process \r, \n, and \t into carriage return, newline, and tab
respectively. Newline still doesn't function in contexts where it can't
(e.g. BRE), but we process it anyways rather than passing
UB \n (escaped ordinary) through to the underlying regex engine.

Adding a --posix flag to disable these was considered, but sed.1 already
declares this version of sed a super-set of POSIX specification and this
behavior is the most likely expected when one attempts to use one of these
escape sequences in pattern space.

This differs from pre-r197362 behavior in that we now honor the three
arguably most common escape sequences used with sed(1) and we do so outside
of character classes, too.

Other escape sequences, like \s and \S, will come later when GNU extensions
are added to libregex; sed will likely link against libregex by default,
since the GNU extensions tend to be fairly un-intrusive.

8a16b7a18f General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

b780b03cbe sed(1): add LEGACY_BSDSED_COMPAT compile-time flag.
In r297602, which included a __FreeBSD_version bump to 1100105, we changed
sed 'i' and 'a' from discarding whitespaces to conform with what GNU and
sysvish sed do.

There are arguments in favor of keeping the old behavior but the new
behavior is also useful for migration purposes. It seems important to at
least consider the case of developers depending on the previous behavior,
so add a CFLAG to enable the old behaviour.

indeed, the same call to add_compunit processing the sole command (given
without -e) passes the *argv verbatim: without making a copy, and without
appending newline.

430f7286a5 Merge ^/user/ngie/release-pkg-fix-tests to unbreak how test files are installed
after r298107

Summary of changes:

- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
  namespacing is kept with FILES appropriately, and that this shouldn't need
  to be repeated if the namespace changes -- only the definition of PACKAGE
  needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
  `tests`. In the event we get to the point where things can be split up
  enough in the base system, it would make more sense to group the tests
  with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
  previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
  bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
  ${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
  and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)

Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.
