* Completely clean up UTF-8 handling in the file filename.c:schwarze2019-05-071-12/+12
| | | | | | | | | | Employ the usual form of an mbtowc(3) loop, eliminating two calls to the bad function step_char() and reducing the number of nested loops by one. This also removes the last caller of the bad function binary_char(), which is consequently deleted. While here, count ASCII C0 non-whitespace control characters as binary (except backspace and, with -R only, escape). OK millert@
* To simplify the upcoming UTF-8 cleanup in less(1), delete supportschwarze2019-02-261-1/+1
| | | | | | | | | | | | | | for ANSI escape sequences introduced by an 8-bit CSI (e.g. "\23343m") because these are neither compatible with UTF-8 nor strictly compatible with pure ASCII and for those introduced by an UTF-8 CSI (e.g. "\302\23343m") because not even xterm(1) supports them at all, not even with a non-default configuration, because both forms are very rarely used, if at all, and because the current code trying to support them doesn't even appear to work according to my tests. Full support for the ESC-[ CSI (e.g. "\033[43m") remains. Tweaks and OK millert@, OK nicm@, and sthen@ agrees with the general direction.
* After fstat(2) failure, trying lseek(2) is useless, so delete it.schwarze2017-10-291-16/+1

* Garrett D'Amore has agreed to moving his copyright line up above thenicm2015-11-061-4/+2

* Replace less with the cleaned-up fork of less 458 maintained by Garrettnicm2015-11-051-587/+233
| | | | | | | | | | | | | D'Amore at https://github.com/gdamore/less-fork. This has significantly less portability goop, has a tidied up code style, uses terminfo instead of termcap, and is has stricter POSIX compliance. Many of our local changes have been accepted upstream: substantial remaining local changes are code to read help files from /usr/share rather than compiling them in, man page and help improvements, and some tweaks to the default options. Review and testing by millert, ok deraadt
