MFC r350425: printf(1): Note that \c only works in %b strings

Renumber copyright clause 4

2017-02-28T23:42:47Z

Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96

Add parameterized position handling to printf(1).

2014-04-21T22:47:18Z

Add a new %n$ option to change the order of the parameters as done in the ksh93 builtin printf (among others). For example: %printf '%2$1d %1$s\n' one 2 three 4 2 one 4 three The feature was written by Garret D'Amore under a BSD license for Nexenta/illumos.

printf(1): Document that %c and precision for %b/%s use bytes, not chars.

2011-05-28T14:32:47Z

This means these features do not work as expected with multibyte characters. This perhaps less than ideal behaviour matches printf(3) and is specified by POSIX.

printf: Allow multibyte characters for ' form, avoid negative codes.

2011-05-28T11:37:47Z

Examples: LC_ALL=en_US.UTF-8 printf '%d\n' $(printf \'\\303\\244) LC_ALL=en_US.ISO8859-1 printf '%d\n' $(printf \'\\344) Both of these should print 228. Like some other shells, incomplete or invalid multibyte characters yield the value of the first byte without a warning. Note that there is no general way to go back from the character code to the character.

printf(1): Move non-bugs from the BUGS section to a new section CAVEATS.

printf(1): Mention effect of '#' modifier on other conversions.

sh: Add printf builtin.

This was removed in 2001 but I think it is appropriate to add it back: * I do not want to encourage people to write fragile and non-portable echo commands by making printf much slower than echo. * Recent versions of Autoconf use it a lot. * Almost no software still wants to support systems that do not have printf(1) at all. * In many other shells printf is already a builtin. Side effect: printf is now always the builtin version (which behaves identically to /usr/bin/printf) and cannot be overridden via PATH (except via the undocumented %builtin mechanism). Code size increases about 5K on i386. Embedded folks might want to replace /usr/bin/printf with a hard link to /usr/bin/alias.
