Allow inner whitespace in the right-hand side of an environment variable
assignment even if it is not quoted (as advertised by the man page).
This fixes a regression wrt RELENG_4 introduced in rev. 1.11.

Problem noted and patch tested by: CHOI Junho <cjh@kr.FreeBSD.org>
Reviewed by: roberto

load_env(), the function that attempts to parse a crontab
line as an environment variable assignment, is broken
and not conformant to its description in the manual page.

I think it is worthwhile to have that fix in 4.6.

Fix a possible NULL reference that would be triggered
by invalid input in /etc/crontab.

Allocate space for arrays of type "char *", not "char **".
Rev 1.8 made the type consistently incorrect.

Noted by: Ben Smithurst <ben@scientia.demon.co.uk>

Fix a situation where a pointer which should point to dynamically
allocated memory was instead pointed to a static string. A later
free() on the value of the pointer was a possible source of reported
"warning: pointer to wrong page" messages from cron.

Use consistent types in sizeof when malloc'ing memory for the
environment.

$Id$ -> $FreeBSD$

Use err(3). Rewrote man page in mdoc format.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Replace my "inane" usage of snprintf to copy strings with strncpy as
used by OpenBSD. (Quite frankly, I think it's perfectly reasonable to
use snprintf to copy strings, given that the semantics for strncpy()
are utterly idiotic and there is no POSIX sstrncpy().)

While I'm at it, incorporate some of OpenBSD's bugfixes to cron.

NOT for 2.2

Close yet another buffer overrun

This commit was generated by cvs2svn to compensate for changes in r2311,
which included commits to RCS files with non-trunk default branches.

Paul Vixie's cron, version 3.0. Munged into bmake format. If this goes
well, expect our two seperate directories for cron and crontab to go away
shortly.
