* Usually, -width Fl (which is 10n) is too wide and hence ugly.schwarze2020-01-161-3/+3
| | | | Change several instances, most of them to the usual -width Ds.
* document octal escape format in %b arguments;schwarze2019-08-021-3/+22

* Fix incorrect character escape.bentley2019-06-021-3/+3
| | | | From Stephen Gregoratto; thanks!
* remove the Ic macro from EXAMPLES, and use a much more standard literal;jmc2018-03-131-15/+10

* Fix two documentation bugs:schwarze2016-11-181-5/+10
| | | | | | | 1. Specifying a precision for the %s format character limits the number of bytes printed, not the number of characters. 2. Document the intentional POSIX violation of ignoring the locale. Feedback and OK jmc@, bentley@.
* Delete useless call to setlocale(3).schwarze2016-11-181-13/+9
| | | | | | | | | | | | While the C library function printf(3) is used here and is locale-dependent, the printf(1) utility does not use the locale dependent parts %lc and %ls. While POSIX requires LC_NUMERIC support, we intentionally don't implement that in printf(3). In summary, no functional change. While here, sort headers and use the usual __dead usage() idiom. Based on a patch from Jan Stary <hans at stare dot cz>. OK bentley@
* fix signed char extension bugs. from fade@cock.li. ok guenther.tedu2016-07-271-4/+4
| | | | | | As a personal remark, I'll add that it's not necessary to cast a value to a function's return type. The compiler is happy to do that for you. But such casts can hide warnings and bugs.

| | | | | program which has had string mismanagement bugs before, probably of the exploitable fashion.. if used in the wrong kind of script..
* Reduce usage of predefined strings in manpages.bentley2015-02-281-4/+4
| | | | | | | | | | | Predefined strings are not very portable across troff implementations, and they make the source much harder to read. Usually the intended character can be written directly. No output changes, except for two instances where the incorrect escape was used in the first place. tweaks + ok schwarze@
* document the special \c escape sequence that can only be used with %b;schwarze2014-10-221-4/+13
| | | | | | | | gap found by guenther@ following a question asked by Frank Brodbeck <fab at split dash brain dot de>; while here, sort escape sequences, this part of the patch from Frank Brodbeck; ok guenther@
* don't use plural "arguments" in SYNOPSIS, since "..." makes itjmc2014-05-252-10/+8

* Use errc/warnc to simplify code.guenther2014-05-201-2/+2
