Drop the vestiges of the pre-POSIX support of `test -t' defaulting to fd
1. It doesn't work and it always succeed since "-t" is treated as a
string by default when no argument (fd) is specified.

This is similar to the emacs mode clear-screen command. Unlike

With the pipefail option set, the exit status of a pipeline is 0 if all
commands succeed, or the return status of the rightmost command that
fails. This can help stronger error checking, but is not a silver
bullet. For example, commands will exhibit a non-zero exit status if
they're killed by a SIGPIPE when writing to a pipe. Yet pipefail was
considered useful enough to be included in the next POSIX standard.
This implementation remembers the value of the pipefail option when
a pipeline is started, as described as option 1) in

Reference the First Edition (1989) of Bolsky/Korn which is about ksh88,
the shell the OpenBSD ksh(1) descends from (via pdksh).
The Second Edition (1995) of the book is about ksh93 which we don't provide.

1. Mark up reserved words intended to appear at the beginning of command
lines with .Ic.
2. Mark up syntax elements intended to appear in the middle of command
lines with .Cm.
This is not only more systematic, but also makes internal search
commands like :tif<enter>, :tstop<enter>, and :t[[<enter> work in
man(1).

The interpretation of the POSIX text is disputed, but it is unlikely
that a change from the traditional behavior was intended.

This simple patch makes the 'command' builtin POSIX-compliant and
consistent with other current shells. It fixes two things:
a) 'command -v' does not find shell reserved words (a.k.a. keywords).
For instance, 'command -v select' outputs nothing but should output
'select'.
b) 'command -pv' always outputs the path of an external command, even
if 'command -p' would execute a builtin. For instance, 'command -p kill'
executes the 'kill' builtin, as expected, but 'command -pv kill' outputs
'/bin/kill'. The '-v' option is supposed to reflect what would actually
be executed, so 'command -pv kill' should output 'kill'. The -p option
sets the PATH to a default system value before doing the search, but
that has no bearing on the fact that builtins take precedence over
external commands.
The patch fixes both issues for 'command' without affecting the
behaviour of the ksh-specific builtin 'whence', which is handled by the
same C function.
Regression test added to obsd-regress.t.

It should be possible to use set +o to save the current shell options,
then modify them at will and later restore them to the saved value.
Therefore the output must not only contain the options which are
currently set, but also the ones that are _not_ set, so a restore
disables them if they are enabled.
