Fix "command not found" handling so that the error message
goes to stderr (after any redirections are applied).
More importantly, in
foo > /tmp/junk
/tmp/junk should be created, before any attempt is made
to execute (the assumed non-existing) "foo".
All this was always true for any command (not found command)
containing a / in its name
foo/bar >/tmp/junk 2>>/tmp/errs
would have created /tmp/junk, then complained (in /tmp/errs)
about foo/bar not being found. Now that happens for ordinary
commands as well.
The fix (which I found when I saw differences between our
code and FreeBSD's, where, for the benefit of PR 42184,
this has been fixed, sometime in the past 9 years) is
frighteningly simple. Simply do not short circuit execution
(or print any error) when the initial lookup fails to
find the command - it will fail anyway when we actually
try running it. The cost is a (seemingly unnecessary,
except that it really is) fork in this case.
This is what I had been planning, but I expected it would
be much more difficult than it turned out....
XXX pullup-8
This file lists the most important changes in the mandoc.bsd.lv distribution.
Changes in version 1.14.4, released on August 8, 2018
--- MAJOR NEW FEATURES ---
* In ASCII output, render mathematical symbols and greek letters
as transliterations conveying the characters' meanings rather
than trying to imitate their shape. Consequently, such characters
can now be used in portable manual pages. All the same, please
limit their use to contexts where they really matter, for example
when showing complicated mathematical formulae.
* First steps towards better support for small screens in HTML
output (responsive design): avoid most style= attributes, in
particular all hard-coded indentations and column widths, and
provide a better mandoc.css style sheet with a @media query,
using em units throughout, and avoiding redundancy in selectors.
* Better HTML output with some more fitting HTML elements, eliminating
needless class= attributes, and avoiding various HTML syntax errors
(element nesting, URL-fragment syntax, duplicate id= attributes).
--- MINOR NEW FEATURES ---
* When a man(1) argument contains a slash, imply -l like in man-db.
* Use TIOCGWINSZ to reduce the default -Owidth and -Oindent during
interactive use on terminals narrower than 79 columns.
* Generated PostScript files are now more than 50% smaller.
* Terminal rendering of eqn(7) is improved in several respects.
* Simplified and nicer output from the mdoc(7) .Lk macro, formatting
all links in-line, even long ones.
* roff(7) \n+ and \n- numerical register auto-increment and -decrement
* roff(7) .nr optional third argument (auto-increment step size)
* Autodetect in ./configure whether the compiler can use -W and -static,
allowing to build on Solaris 10 and 11 without any configure.local.
--- RELIABILITY BUGFIXES ---
* Only activate UTF-8 output when the user really selected UTF-8,
not some other multibyte character encoding.
* Prevent excessive .ll arguments from generating infinite output.
* Fix out of bounds accesses to parse buffers that could happen when
using renamed or user defined macros after roff(7) conditionals.
* Avoid an assertion failure in certain .Bl -column lists.
* Avoid a NULL pointer access on deroff() failure after '.SS ""'.
* Fix a segfault that could be triggered by two invalid .Dt macros.
* Fix two syntax errors in generated PDF files.
* Properly state the page size in generated PostScript files.
* Close a memory leak caused by missing gzclose(3).
* Fix misformatting of man(7) documents lacking .SH macros
in PostScript and PDF output.
* And many minor bugfixes.

Changes in version 1.14.3, released on August 5, 2017
--- BUG FIXES ---
* man(7): Do not crash with out-of-bounds read access to a constant
array if .sp or a blank line immediately precedes .SS or .SH.
* mdoc(7): Do not crash with out-of-bounds read access to a constant
array if .sp or a blank line precede the first .Sh macro.
* tbl(7): Ignore explicitly specified negative column widths rather than
wrapping around to huge numbers and risking memory exhaustion.
* man(1): No longer use names that only occur in the SYNOPSIS section.
Gets rid of some surprising behaviour and bogus warnings.

Leah Neukirchen (Void Linux), Markus Waldeck (Debian),
Peter Bui (nd.edu), and Yuri Pankov (illumos) for bug reports.
Changes in version 1.14.2, released on July 28, 2017
--- MAJOR NEW FEATURES ---
* New mdoc(7) -Tmarkdown output mode.
* For -Thtml, implement internal hyperlinks pointing to authoritative
definitions of various syntax elements, similar to the ctags(1)-like
less(1) :t internal searching in terminal mode.
* Provide a superset of the functionality of the former mdoclint(1)
utility and a new -Wstyle message level with several new messages,
including validity checking of .Xr cross references.
* tbl(7): Implement automatic line breaking inside individual table
cells, and several other formatting improvements.
* eqn(7): Complete rewrite of the lexer, resulting in several bugfixes.
* Continue parser unification, in particular allowing generation
of syntax tree nodes on the roff(7) level, allowing implementation
of many additional roff requests.
--- REMOVED FUNCTIONALITY ---
* Delete the manpage(1) utility. It was never enabled in any release.
* Delete the -Txhtml command line option. It has been an obsolete
alias for the -Thtml output mode for more than two years.
--- MINOR NEW FEATURES ---
* -Tlint now puts parser messages on stdout instead of stderr,
making commands like "man -l -Tlint *.1" useful.
* mdoc(7): Various .Lk formatting improvements.
* mdoc(7) -Thtml: Better CSS for .Bl lists.
* man(7): Implement the .MT/.ME block macro (mailto hyperlink).
* man(7): Implement the .DT macro (restore default tab positions).
* man(7): Improved support for manuals generated with reStructuredText
by partial support for the \n[an-margin] number register.
* man(7) -Thtml: Support deep linking to .SH and .SS headers.
* tbl(7): Implement the "allbox" table option.
* tbl(7): Implement the column spacing and the 'w' (minimum column
width) layout modifiers.
* tbl(7): Significant improvements of the manual page.
* eqn(7): Much improved font selection, including recognition of
well-known function names, and a few other formatting improvements.
* eqn(7) -Thtml: Use <mn> and <mo> in addition to <mi>.
* roff(7): Implement the .ce (centering), .mc (margin character),
.rj (right justify), .ta (define tab stops), .ti (temporary indent),
.als (macro alias), .ec and .eo (escape character control),
.po (page offset), and .rn (macro rename) requests.
* roff(7) .am: Implement appending to mdoc(7) and man(7) macros.
* roff(7): implement the \h (horizontol motion), \l (horizontal
line drawing), and \p (break output line) escape sequences,
and also several additional character escape sequences.
* roff(7): Implement the 'd' conditional (macro or string defined).
* man.cgi(8) now uses pledge(2), too.
* regress.pl(1): simpler user interface, better summary output,
simpler code, and no more recursion.

The previous place (pserialize_switchpoint) was not a good place because at that
point a suspect thread is already switched so that a backtrace gotten on
a KASSERT failure doesn't point out where a context switch happens.
Reuse the body of child_attach_to_its_parent for a test attaching to a
stopped parent.
As a workaround to ATF framework (atf-run), run this test in a subprocess.
The raise(SIGSTOP) call breaks the pipe from atf-run, that is polling
whether a process is in order.
According to code inspection the poll(2) call in safe_poll() receives
EINTR and this tears down the test.
This test passes.
Add a url for ath-hal to the FreeBSD svn repo and update rev
Update bsd-family-tree url to link directly to svnweb
Still to complete the list and repass with versions in our tree.
