Expand *n't contractions.

Sort sections.

Tidy up synopsis.

Add the -n maxrec option as an alias for -maxrec for compatibility with

Use .Pa for wtmp.

Use `The .Nm utility'

Add a new "-y" flag which causes the year to be included in the

wtmp files.

mdoc(7) police: removed HISTORY info from the .Os call.

mdoc(7) police: add missing .Ar in SYNOPSIS.

Implement snapshots. The new -d option allows the user to find out
who was logged in at a certain time and date.

mdoc(7) police: remove hard sentence breaks.

mdoc(7) police: use the new features of the Nm macro.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Add s and w flags to show duration in or with seconds.

Fixed a bug that caused last(1) to be extremely slow in some cases, and
made other performance improving changes. This improves the performance
of last(1) by as much as 32 times in some cases, and in more typical cases
is about twice as fast.
Added a BUGS section to the manual page to describe the behavior of last(1)
when a login shell terminates abnormally (and thus doesn't write a logout
record to the wtmp file).

This commit was generated by cvs2svn to compensate for changes in r1590,
which included commits to RCS files with non-trunk default branches.
