- correct `SYNOPSIS';
- improve macro usage;
- mention argument name for `-f' (and change list width for it);
- correct misplacement of periods (`.') and a parenthese (`(');
- fix typo;
- bump date.

we opened is the one we expected to get. Also use O_NOFOLLOW to help
avoid even opening devices, which sometimes produce side effects.

depend on new devname_r(3) as heart. Add /dev/pts magic directly to
devname(3). While it can lead to returning non-existing paths, the
behavior is more consistent that way. Drop caching layer in devname(3),
it doesn't buy anything for the common case of having access to the
database. Teach devname(3) proper fallback behavior of scanning /dev.
Create both old-style and new-style database for now in /etc/rc.d/sysdb.
- bump the manpage's date (because of the next change);
- note that cp(1) does not preserve hard links (even with `-R'),
and refer to pax(1) there as well as in the `SEE ALSO' section
for such functionality (this change is based upon a similar note
in FreeBSD's version of the manpage);
- change a wording, for more overall consistency.
state of the stream. Change argument of the seek function to funopen() from
fpos_t to off_t. Make f{g,s}etpos() use the new fpos_t struct, while providing
backwards compatible entry points. Approved by releng@
char 160 in the input to csh, lead it to an infinite loop, because tcsh tables
counted this as a space character, but the word logic switch does not. Change
that character tables, so that this does not count as a spacing character
anymore, by syncing the table with the one from tcsh.
- error out when an unknown specifier is used. Do this in f_msgfmt(),
before dd(1) starts operation.
- allow buffer_write() to flush the internal buffer even when NULL is
passed as parameter.
Some whitespace fixes too.

to specify messages in a more usable (or parseable) format like
human-readable values.
My intent is to re-use this for building image files and quick I/O
benchmarking.
