Correct date. It seems to be 2012.

Detect file modification properly by using tv_nsec.

POSIX 2008 standardizes st_mtim, meaning we can simply use nanosecond
precision to detect file modification.

The last big commit: let usr.sbin/ use WARNS=6 by default.

are synonymous, but ensure seems slightly closer and does not have the
connotation of buying insurance.

Make mppath and masterpasswd pointers instead of arrays, and initialize
them to point at static strings that contain the default paths. This
makes 'vipw -d' work again (I broke it in rev 1.21; apologies for taking
so long to fix it.)

Don't call warn() without a format string.

Remove single-space hard sentence breaks. These degrade the quality

bad examples for new-comers to mdoc.

Replace the -q option to pwd_mkdb with a test for PW_SCAN_BIG_IDS in
the environment. This allows big ID warnings to be suppressed for
vipw and chpass as well.

Since the environment variable test is only performed for callers
of pw_scan() that do not set pw_big_ids_warning, the test can still
be overriden. Currently, chpass and pwd_mkdb are the only users
of pw_scan() and neither of them overrides the environment variable
test.

Do not rely on malloc() to zero-fill allocated memory, since it is
not documented as doing so. This fixes a potential segmentation
violation.

$Id$ -> $FreeBSD$

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.

Move call to umask(0) back into pw_util(), because the latter
function is also used by chpass(1) and passwd(1).

Force umask to 077 (instead of 000) during the edit phase, to get
secure permissions in case the user attempts to save something to
a file of his own.

Move umask stuff out of pw_init() into main() for better visibility
of overall umask tweaking logic.

oops. Fix indentation of the 'for' loop I just added.

Handle the race condition where vipw may lock a password file which has
just been replaced. After our lock succeeds we check if st_nlink is 0
and if it is we close the descriptor and retry our open/lock sequence.

Since vfork() was changed to fork(), we have to pass errno back from the
child to the parent somehow.

Calls one or more of malloc(), warn(), err(), syslog(), execlp() or
execvp() in the child branch of a vfork(). Changed to use fork()
instead.

Some of these (mv, find, apply, xargs) might benefit greatly from
being rewritten to use vfork() properly.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Implement incremental passwd database updates. This is done by ading a '-u'
option to pwd_mkdb and adding this option to utilities invoking it.
Further, the filling of both the secure and insecure databases has been
merged into one loop giving also a performance improvemnet.
Note that I did *not* change the adduser command. I don't read perl
(it is a write only language anyway).
The change will drastically improve performance for passwd and
friends with large passwd files. Vipw's performance won't change.
In order to do that some kind of diff should be made between the
old and new master.passwd and depending the amount of changes, an
incremental or complete update of the databases should be agreed
upon.

Small NIS tweak: frob pw_error() a little so that it can say either
'NIS information unchanged' or '/etc/master.passwd unchanged'
depending on which was is being modified (conditional on -DYP).

This is to save me the trouble of writing a whole other error
routine (nis_error()?) for the upcoming changes to passwd and
chpass.

Remove trailing whitespace.
