6781fcee0f POSIX says that octal escapes have the format \ddd in the format string,
but \0ddd in a %b argument, with a length restriction of 3 octal digits
in either case. This seems silly, but it needs to be right so it's possible
to write an octal escape followed by an ordinary digit. Solaris printf(1)
and GNU printf(1) also behave this way.

Example: "printf '\0752'" now produces "=2" instead of garbage.

aed8bcfc2b Replace buggy for-loops to skip certain character with strspn(). If *fmt was
'\0' (eg in the invocation 'printf %'), the for-loop would miss the terminating
null character.

f5e55fd604 Support the L modifier for floating-point values as an extension.
When L is omitted, double precision is used, so printf(1) gives
reproducable results.  When L is specified, long double precision is
used, which may improve precision, depending on the machine.

23afcbf88f Allow %' to be used as a format flag by printf(1). This makes it
possible to print the thousands separator in the locale setups that
have one, by something like this:

    $ env -i LC_NUMERIC=en_US.ISO8859-1 ./printf "%'0.2f\n" 12345

This bug has been around for 22 months... either nobody uses printf
with floating-point values, or people are forgetting to check their
return codes.

d1fecdf4b5 - printf shouldn't bail out if a conversion fails, it should just keep
processing them.
 - \c escape to immediately stop output (similar to echo's \c)
 - \0NNN should be allowed for octal character escapes (instead of just \NNN)
 - %b conversion, which is like %s but interprets \n \t etc. inside the
   string is missing.

And I may not be any poet, but in lieu of an in-tree regression test:
ref5% ./printf '%s%b%b%c%s%d\n' 'PR' '\0072' '\t' '3' '56' 0x10

d9613ea383 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.

96265e088e Remove the printf builtin command from sh(1), which command is not
used so often that it's worth keeping it as a builtin.

Now that all the printf invocations from within the system startup
scripts, we can safely remove it.

No MFC is planned so far because it may break compatibility and
