f697348034 Reinstate revision 1.11:
BDECFLAGS; ANSIfy; use EXEC instead of "exec " where appropriate; use
proper types (size_t, int); use proper variable names for certain things;
get rid of static 'cache' style stuff by moving and sanitizing the
original SHELL checking code to main(), this also makes it easier to
free() the string; rename file-scope system() to exec_shell(); use
snprintf() everywhere instead of sprintf(); actually remember to free()
other malloc()'d char pointers in main().

I left out the -s option in this revision along with getusershell()
checking because of objections made by Warner Losh <imp> and Garrett
Wollman <wollman>.  I agreed with their assertions that such code was
unnecessary in a program like this.

I dare people to make this coredump now.

Some suggestions:	nectar (snprintf() truncate checking)

and make sure it works next time.

fbd7649d29 Document new -s option: pass a shell to apply(1) when the desired shell
isn't found in /etc/shells.

c494ed80cd BDECFLAGS; de-__P()-ify, ANSIfy, use snprintf() instead of sprintf(),
especially on strings passed from argv; rename system() to exec_shell(),
and make it static; use strlcpy() and make sure it works; use proper
type (size_t) to be passed to malloc()/realloc().

Use getusershell() to make sure the SHELL environment variable passed is
safe to use.  Add new option -s to allow anal users to pass things like
perl; this option is here along with getusershell() checking since the
such checking is only intended to affect things like suidperl that might
call apply(1).

6ad135868c fork() -> vfork()
This would have been commit #2 which was "Obtained from: BSD/OS" except
their code is buggy (they call err() if the execl() fails, which will
incorrectly call exit()), so instead this is:

3be5f1f5ce 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.

1fd98d7d88 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.
