This knob removes the tools that are exclusively used to view and
maintain the databases maintained by utmpx, namely last, users, who,
wtmpcvt, ac, lastlogin and utxrm.
The tool w is not in this list, because it has some other functionality
which is unrelated to utmpx; it is hardlinked to the uptime tool.

Ignoring the parameter with the unknown options is unlikely to be what was

in grotty(1). This makes it possible to view colorized manpages in
color.
When MANPAGER environment variable is set, use it instead of PAGER.
Why another environment variable, one might ask? With color output
enabled, both a terminal and a pager should support the ANSI color
escapes. On a supporting terminal, less(1) with option -R would be
such a pager, while "more -s" (the current default pager for man(1))
will show garbage. It means a different default pager is needed when
color output is enabled, but many people have PAGER set customary,
and it's unlikely to support ANSI color escapes, so introducing yet
another variable (MANPAGER) seemed like a good option to me:
- if MANPAGER is set, use that unconditionally;
- if you disable color support (it is by default), and don't set
MANPAGER, you get an old behavior: -P pager, $PAGER, "more -s",
in that order;
- if you enable color support (by setting MANCOLOR), and don't set
MANPAGER, we ignore PAGER which is unlikely to support ANSI color
escapes, and you get: -P pager, "less -Rs", in that order;
- you might have good reasons for different man(1) and general
purpose pagers;
- later versions of GNU man(1) support MANPAGER.
If set to a numeric value, used as the width manpages should be
displayed. Otherwise, if set to a special value ``tty'', and
output is to a terminal, the pages may be displayed over the
whole width of the screen.
rather than at the bottom of the manpage.

idle threads). The process is displayed by default (subject to whether or
not system processes are displayed) to preserve existing behavior. The
system idle process can be hidden via the '-z' command line argument or the
'z' key while top is running. When it is hidden, top more closely matches
the behavior of FreeBSD <= 4.x where idle time was not accounted to any
process.

This means these features do not work as expected with multibyte characters.
This perhaps less than ideal behaviour matches printf(3) and is specified by
POSIX.
Examples:
LC_ALL=en_US.UTF-8 printf '%d\n' $(printf \'\\303\\244)
LC_ALL=en_US.ISO8859-1 printf '%d\n' $(printf \'\\344)
Both of these should print 228.
Like some other shells, incomplete or invalid multibyte characters yield the
value of the first byte without a warning.
Note that there is no general way to go back from the character code to the
character.
If WITH_BSD_GREP is not set, it will be 'bsdgrep' and GNUgrep will be
'[ef]grep'. Otherwise, BSD-grep will be the grep family, and GNUgrep
will be 'gnugrep'.

file and processes information retrieval from the running kernel via sysctl
in the form of new library, libprocstat. The library also supports KVM backend
for analyzing memory crash dumps. Both procstat(1) and fstat(1) utilities have
been modified to take advantage of the library (as the bonus point the fstat(1)
utility no longer need superuser privileges to operate), and the procstat(1)
utility is now able to display information from memory dumps as well.
The newly introduced fuser(1) utility also uses this library and able to operate
via sysctl and kvm backends.
The library is by no means complete (e.g. KVM backend is missing vnode name
resolution routines, and there're no manpages for the library itself) so I
plan to improve it further. I'm commiting it so it will get wider exposure
and review.
We won't be able to MFC this work as it relies on changes in HEAD, which
was introduced some time ago, that break kernel ABI. OTOH we may be able
to merge the library with KVM backend if we really need it there.

Let groff pass the -c flag to grotty, which will turn off ANSI

mangled by col(1) and this will result in garbage output.
This makes man(1) work together with textproc/groff, in case the
user decided to delete the old groff from base (-DWITHOUT_GROFF).
