reset on exec as preserving it across exec is not necessary for its
original purpose and has security and usability concerns.
Many thanks to Ricardo Branco (rbranco (at) suse.de) who did an
independent implementation, caught that /dev/fd/* needed to be
handled, and provided a port of the illumos test suite. Thanks
to tb@ for assistance with that.

The mdoc(7) .Ft macro does not need quoting of its arguments, but about2025-06-13T18:34:00+00:00schwarze2025-06-13T18:34:00+00:00urn:sha1:d939c0f8976619330bcf368e12700a6ab1d14f99
10% of our manual pages using this macro employed useless quoting anyway.
Remove these quotes such that they do not incite fear, uncertainty,
and doubt in developers who happen to look at these pages.
jmc@ and tb@ agree with the direction.

POSIX-2008 requirements for setting the underlying file position when
flushing read-mode streams, and make an fseek()-after-fflush() not
change the underlying file position. This commit fixes some minor
problems of the previous.

Delete bad advice about abusing malloc_options = "X" as a production2025-05-27T12:40:37+00:00schwarze2025-05-27T12:40:37+00:00urn:sha1:b1dd45ef5fd4c83b819456f207db22005aee5041
feature to terminate the program when out of memory. Application code
should always handle failure of library functions properly. So if you
want your program to terminate, write something like
| p = malloc(...);
| if (p == NULL)
| err(1, NULL);
and don't abuse malloc_options.
Direction suggested by otto@ after anton@ pointed out that this very old
text still used an outdated data type for malloc_options and potentially
failed to define its value at compile time.

binaries had become unlinkable. Change the libc definition to weak to solve
that, and to "const char * const" so that noone will try to set it late.
It must be stable before the first malloc() call, which could be before
main()...
