da52b4caaf Remove the advertising clause from UCB copyrighted files in usr.bin. This 
is in accordance with the information provided at
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

Also add $FreeBSD$ to a few files to keep svn happy.

3f8c1392ef Update the date on the man-page to reflect the date that the '-u name' 
change was committed, instead of when I had first started writing it...

a414225db1 Add the '-u name' option to the env command, which will completely unset 
the given variable name (removing it from the environment, instead of
just setting it to a null value).

2f739d3c1a Undo r1.14 to env.c. While it is unusual for environment variables to 
start with a '/', they are more supported (by POSIX and SUSv3) than
filenames which have an '=' in them.

8fbe7ebf7d Add the '-S' and '-P' options. The '-S' option can be used to split 
apart a string, and supports some text substitutions.  This can be
used to provide all the flexibility (and more!) that was lost by recent
changes to how the kernel parses #!-lines in shell scripts.

The '-P' option provides a way to specify an alternate set of directories
to use when searching for the 'utility' program to run.  This way you can
be sure what directories are used for that search, without changing the
value of PATH that the user has set.  Note that on FreeBSD 6.0, this
option is worthless unless the '-S' option is also used.

52964a40af Removed (after the env(1)/printenv(1) split) extraneous arguments 
to the .Nm macro.

14f566d3ca Split the env(1) manpage off from printenv(1); there is not much point 
in keeping them together. Mention that printenv is obsolescent.
