The standard is somewhat unclear, but on the balance, I believe that the
phrase “the rest of the input line” should be interpreted to mean the
rest of the input line including the terminating newline if and only if
there is one. This means the current implementation is incorrect on two
points:
- First, it suppresses the previous line's newline in the '1' case.
- Second, it unconditionally emits a newline at the end of the output
for non-empty input, even if the input did not end with a newline.
Resolve this by rewriting the main loop. Instead of special-casing the
first line and then assuming that every line ends with a newline, we
remember how each line ends and emit that either at the beginning of
the next line or at the end of the file except in the one case ('+')
where the standard explicitly says not to.
While here, try to reduce diff to upstream a little and update their
RCS tag to reflect the fact that while we've diverged significantly
from them, we've incorporated all their changes. Remove the useless
second RCS tag.
We also update the tests to account for the change in interpretation
of the '1' case and add a test case for unterminated input.

In most cases, usage does not return, so mark them as __dead2. For the
cases where they do return, they have not been marked __dead2.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
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.
No functional change intended.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.
