Every version of patch since the first one posted to mod.sources in 1985 have
included a heuristic for coping with the state of email messaging at the
time. This heuristic would add up to 4 blank lines to a patch if it thought it
needed it. The trouble is, though this causes at least one bug.
The bug in my case is that if you have a context diff whose last hunk only
deletes 3 or fewer lines, then if you try to reverse apply it with -R, it will
fail. The reason for this is the heuristic builds an internal representation
that includes those blank lines. However, it should really replicate the lines
from the pattern lines line it would any other time, not assume they are blank
lines. Removing this heuristic will prevent patch from misapplying the lines
removed after applying a 'fuzz' factor to the previous blank line in the file. I
believe this will only affect 'new-style' 4.3BSD context diffs and not the
older-style 4.2BSD diffs and plain, non-context diffs. It won't affect any of
the newer formats, since they don't use the 'omitted' construct in the same way.
Since this heuristic was put into patch at a time when email / etc ate trailing
white space on a regular basis, and since it's clear that this heuristic is the
wrong thing to do at least some of the time, it's better to remove it
entirely. It's not been needed for maybe 20 years since patch files are not
usually corrupted. If there are a small number of patch files that would benefit
from this corruption fixing, those already-currupt patches can be fixed by the
addition of blank lines. I'd wager that no one will ever come to me with an
example of a once-working patch file that breaks with this change. However, I
have 2 patches from the first 195 patches to 2.11BSD that are affected by this
bug, suggesting that the relative frequency of the issue has changed
signficantly since the original heuristic was put into place.

My change to allow bootstrapping pwd_mkdb (r363992) resulted in i386 build
failures because the bootstrap header was being included in non-bootstrap chpass.
Dropping the no longer required pwd_mkdb include path from chpass fixes
the build, but to be certain that the failure doesn't get re-introduced,
I've also moved the bootstrap pwd.h into a subdirectory so that adding
-I${SRCTOP}/usr.sbin/pwd_mkdb doesn't pull it in.

libregex is incomplete, but it's a bit less buggy than the in-base
libgnuregex and mostly OK.
While here, rename -DIWTH_GNU -> -DWITH_GNU_COMPAT; the option implies
that we're compatible with the GNU counterpart, not that we're including GNU
anything.
The tests compare the command output (including of error cases) with the
expected output and exit code.
Not all tests are executed, since some expect to have a known good bc and
dc binary installed and compare results of large amounts of generated data
being processed by both versions to test for regressions.
This version omits the printing of a copyright header in interactive mode
and the dc command now exits after execution of the commands passed via -e
or -f instead of switching to interactive mode. To pass further commands
via STDIN when dc has been invoked with -e or -f, add "-f -" to the
parameter list.
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.
It's currently unclear to me how this could have worked previously; \n here
is not a literal newline but actual '\' 'n', and was getting passed to the
underlying regex engine as such. regex(3) does not translate this to a
newline, and this became an error because we don't really allow escaping
of arbitrary ordinary characters anymore.
Run the pattern strings through printf to make sure we're dealing with real
newlines before passing them through to atf_check, which ultimately feeds
them directly to regcomp(3).
This fix is different than that will be needed for sed, in that this is the
proper way to inject newlines into search strings as long as regex(3)
won't combine \ + n as folks might expect.

The current localedef simply assumes that the locale headers on build system
are compatible with those on the target system which is not necessarily true.
It generally works on FreeBSD (as long as we don't change the locale headers),
but Linux and macOS provide completely different locale headers.
This change adds new bootstrap headers that namespace certain xlocale
structures defined or used by in the headers that localdef needs.
This is required since system headers *must* be able to include the "real"
locale headers for printf(), etc., but we also want to access the target
systems's internal locale structures.

Currently, "install -s -S" behaviour is inefficient for upgrade.
First it finds that destination file already exists and copies
source file to temporary file. Then it calls strip(1)
with name of temporary file as single agrument and our strip(1) creates
another temporary file in the /tmp (or TMPDIR) making another copy
that is finally copied to DESTDIR third time.
Meantime, strip(1) has an option "-o dst" to specify destination
so install(1) is allowed to skip initial copying from obj to DESTDIR.
This change makes it do so.
Take a look at https://reviews.freebsd.org/D25551 for details
and efficiency numbers (in short: upto 32% gained for installword).

This version fixes a regression with regard to tradtional behavior of the
non-standard FreeBSD option "-e". In the previous version "-e quit" caused
bc to exit before any computations had been performed, since all -e option
parameters were concatenated and parsed as a whole, with quit causing the
program to exit as soon as it was parsed. This version parses and executes
commands passed with -e one by one and only exits after all prior commands
have been executed.
This commit is not a SVN merge, since the vendor import had been performed
after the import to contrib. Instead the contents of contrib/bc has been

These implementations of the bc and dc programs offer a number of advantages
compared to the current implementations in the FreeBSD base system:
- They do not depend on external large number functions (i.e. no dependency
on OpenSSL or any other large number library)
- They implements all features found in GNU bc/dc (with the exception of
the forking of sub-processes, which the author of this version considers
as a security issue).
- They are significantly faster than the current code in base (more than
2 orders of magnitude in some of my tests, e.g. for 12345^100000).
- They should be fully compatible with all features and the behavior of the
current implementations in FreeBSD (not formally verified).
- They support POSIX message catalogs and come with localized messages in
Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze,
and Russian.
- They offer very detailed man-pages that provide far more information than
the current ones.
The upstream sources contain a large number of tests, which are not
imported with this commit. They could be integrated into our test
framework at a latter time.

Sort(1)'s radixsort implementation was broken for multibyte LC_CTYPEs in at
least two ways:
* In actual radix sort, it would only bucket the least significant
byte from each wchar, ignoring the 24 most-significant bits of each
unicode character.
* In degenerate cases / "fast paths," it would fall back to another
sorting algorithm (default: mergesort) with a bogus comparator
offset. The string comparison functions in sort(1) take an offset
in units of the operating character size. However, radixsort was
passing an offset in units of bytes. The byte offset must be
divided by sizeof(wchar_t).
This revision addresses both discovered issues.
