- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

- Use errx(3) instead of err(3) when checking if snprintf(3) succeeded.
snprintf(3) doesn't set errno in the tested cases.
- If the same argument reference (for example %1) was specified more than
once, the command didn't necessarily fit to the final command buffer. Fix
this using a dynamic sbuf buffer. Add a few regression tests for the case.

No objections: freebsd-hackers

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

It's ``apply echo *'' that is similar to ``ls -1'', not ``apply echo a*''.

Revert previous commit, from Bruce:
This is a style bug. err() is declared is non-returning so that every
use of it doesn't need to be encrufted with NOTREACHED. It's too bad
that only gcc understands the declaration.

Asked by: bde@

Add NOTREACHED after err() inside of a switch statement.

WARNS=4

Use `The .Nm utility'

Minor whitespace nit.

Remove leaf node WARNS?=2 (that mainly I added). This should
help the GCC3 transition and CURRENT in general.

Style improvements recommended by Bruce as a follow up to some
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

Use __FBSDID().

Revert to version 1.16 which was more correct than either of my attempts.

Remove unnecessary casts.

The original (1.16) code was mostly correct, but this version is
far clearer.

Fix bogus checking of snprintf() by decreasing the remaining size of the
string after each successful snprintf() call. This makes apply(1) work
*correctly*, although the whole snprintf() deal really should be redone.

Bug noted by: nectar (about 3 weeks ago)

Fix numerous style(9) bugs: Put #define's before declarations; sort the
declarations & their arguments; use only one tab after types; restore the
type of argv to sync with src tree style; sort new variables under main();
fix continuation indents; remove extra blank line before free()'s. Still
to do: fix snprintf() handling as nectar & bde suggested to me.

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.

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

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).

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:

$Id$ -> $FreeBSD$

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.

Tweaks to allow compiling -Wall (mostly adding "const" to char rcsid[]).

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.
