0ba01198fc 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.

fd757c50f6 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.

6ac6319b32 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

8c423a998e Make it possible for the %[eEfgG] formats to not result in an error 
being reported by /usr/bin/printf.

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.

ab5a295bdc - 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

9f5b04e925 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.

018d9f6237 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
violate POLA.

the purpose of the style guideline which they contravene is to reduce
