The previous expression borked if a username had a plus or hyphen in it.
This is needlessly restrictive- at leSt a hyphen in the middle is valid.
Instead of playing this game, let's just assume the username can't contain a

Revision 316342, which introduced the anticongestion feature, failed to
consider that the periodic scripts are executed by a recursive invocation of
periodic. The recursive invocation wrongly cleaned up a temporary file that
should've been cleaned up only by the original invocation. The result is
that if the first script that requests an anticongestion sleep runs after
the security scripts, the sleep won't happen.
Fix this bug by delaying cleanup until the end of the original invocation.

In 2011, r218961 removed local code for rotating logs in favor of using the
rotate_log command in etc/rc.d/accounting. If the accounting service is
activated then subsequently de-activated in rc.conf but still remains active
in periodic.conf, then you get an error message every day in the periodic
jobs about being unable to rotate the logs.
With this change to use "onerotate_log", the log rotation will happen the
first time periodic daily runs after accounting was disabled but periodic
accounting was left enabled. After that happens once, the /var/account/acct
will no longer exist, which results in a different path through the periodic
code and no more error messages will appear (unless daily_show_badconfig is
set, in which case the admin will be told that periodic security processing
is enabled but the accounting file is not present).
This is only a partial fix for the problems reported in PR 202203.

When called with an absolute pathname, periodic should attempt to execute
every script in that directory. If the directory does not exist, it should
print an error and exit 1. Due to a copy/paste mistake in r231568, it exits
0 in that case.

Multiple periodic scripts sleep for a random amount of time in order to
mitigate the thundering herd problem. This is bad, because the sum of
multiple uniformly distributed random variables approaches a normal
distribution, so the problem isn't mitigated as effectively as it would be
with a single sleep.
This change creates a single configurable anticongestion sleep. periodic
will only sleep if at least one script requires it, and it will never sleep
more than once per invocation. It also won't sleep if periodic was run
interactively, fixing an unrelated longstanding bug.

periodic(8) already handles the security_show_{success,info,badconfig}
variables correctly. However, those variables aren't explicitly set in
/etc/defaults/periodic.conf or anywhere else, which suggests to the user
that they shouldn't be used.

One thing I'm _not_ doing is recommending setting security_output to
/var/log/security.log or adding that file to /etc/newsyslog.conf, because
periodic(8) would create it with default permissions, usually 644, and
that's probably a bad idea.
