* Delete what remains of the support for combining characters intoschwarze2019-09-021-13/+4
| | | | | | | | | | | | | | ligatures: it was incomplete (only for the Arabic script and only for the single ligature LAM WITH ALEF) and it was implemented in a way that is unsustainable (with a static table inside less). If we ever want ligature support, we are better off making a fresh start. However, for languages like Arabic and Persian, even that wouldn't really be useful without having bidirectional support first. OK millert@ (and also considering comments from Mohammadreza Abdollahzadeh, Evan Silberman, and benno@)

* UTF-8 cleanup in the function cmd_putstr().schwarze2019-05-151-18/+5
| | | | | | This function is only ever called with constant ASCII string arguments, so actually it doesn't need any UTF-8 handling whatsoever. OK millert@

* Replace less with the cleaned-up fork of less 458 maintained by Garrettnicm2015-11-051-459/+249
| | | | | | | | | | | | | 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
