Change or add history. I checked the 1bsd archives and this first
appeared in 1BSD (before it was known as 1BSD). I looked at code and
later sccs history to confirm. In the case of rewritten code, we are
not consistent in manpages indicating that history.

patch from from Snader_LB via IRC.

- mention "The following options are available:"

- improve grammar

- provide useful tip about -x

support reading wtmp/wtmpx from stdin with -f -

from bin/35329 by David A. Holland

Remove trailing whitespace, and use .Sq instead of manual quoting.

PR/26934: Curt Sampson: Add -x flag to process wtmpx files that don't end
in `x'.

Options without arguments are combined in SYNOPSIS; new sentence, new line.

Add -n flag to print numeric entries.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.

Bump date. Sort options, sort SEE ALSO.

Add wtmpx support.

New sentence, new line.

Include -T in the synopsis.

Extend the -T option show that it shows the year as well as seconds.
Also print the full time on interrupt and exit, regardless of the
-T setting. Replace all uses of asctime()/ctime() and magic number
offsets within their return strings with strftime().

Fixes PR bin/5311 from Geoff Wing and much more.

branches: 1.6.10;
More and more .Os cleanups. .Os is defined in the tmac.doc-common file,
so we shouldn't override it with versions in the manpages. Many more to
come.

restructure as a single level if/then/elif/else

Do not access out of bounds argv when mixing non-getopt -<digit> arguments
with regular getopt-handled options.
Fixes PR bin/32596.

Remove extra ; found by gcc-2.95 and reported in port-vax.

Add -n to usage.

Add -n flag to print numeric entries.

Homogenize usage messages: make the 'usage' word all lowercase, as this seems
to be the most common practice in our tree.

Move UCB-licensed code from 4-clause to 3-clause licence.

use bounded string op/asprintf

Fix typo in error message.

Sync usage with options; sort option string; handle N instead of
non-existing U option.

#undef TYPE(a) is not legal. Change to #undef TYPE /*(a)*/

Add wtmpx support.

Fix botch in previous - include the day of the month in the output!

Don't declare 'extern opt*' getopt variables.

Avoid bogus warnings produced by gcc-2.8.1 where it wants field widths to be
ints and copmplains if they are unsigned ints!

Add { and } to shut up egcs. Reformat the more questionable code.

- use an array MAXHOSTNAMELEN+1 size to hold hostnames
- ensure hostname from gethostname() is nul-terminated in all cases
- minor KNF
- use MAXHOSTNAMELEN over various other values/defines
- be safe will buffers that hold hostnames

Tidy up: we no longer need FIRSTVALID for its original purpose, so change
the name of the symbol to something that applies to the remaining use.

When the wtmp file is empty, for the "wtmp[x] begins..." output, use
the last mod time of the wtmp file (in practice, the time it was last
rotated, which is when it begins) instead of the current time, which
wasn't ever particularly useful. PR 39444.

Keep track of the timestamp of the last (thus oldest) record seen and use
it to print "wtmp[x] begins" at the end, instead of knowing where to look
in the final utmp buffer to get a final timestamp out. This is both tidier
and fixes a problem with wtmpx files, which is that if the header record
is missing (which it seems to be on my machines) it would fetch the wrong
time out, and if you happened to have a one-record wtmp file it would use
the current time instead. This change restores the traditional behavior
of printing the time of the oldest record in the file, and if no records
are present to use the current time.

It might be a bug that wtmpx files don't seem to have the header
record they supposedly ought to.

Respect the environment variable TMPDIR if set.

Pointing before a memory object is not proper C. Use an index instead of
pointer arithmetic.

- Applied patch by David Holland from PR bin/35354.
- Use EXIT_SUCCESS/EXIT_FAILURE instead of 0/1.
- Additional check for regular file.
- Use pread() instead of lseek() + read().
- Check for partial read to prevent out-of-bounds memory access.
- Added FIXME to onintr(): This is no proper signal handler albeit might
not really matter here.
