We've ifdef'd out the copyright strings for some time now. Go ahead and
remove the ifdefs. Plus whatever other detritis was left over from other
recent removals. These copyright strings are present in the comments and
are largely from CSRG's attempt at adding their copyright to every
binary file (which modern interpretations of the license doesn't
require).

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.
'y' does not handle bracket expressions, treat '[' as ordinary character
and do not apply bracket expression checks (GNU sed agrees).

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.

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

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.

We don't generally support the weird case of regular expresions delimited
by an opening square bracket ('[') but POSIX says that inside
bracket expressions, escaping is not possible and both '[' and '\'
represent themselves.

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.

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.
