* Add ?o to prompt strings, to detect whether an OSC 8 link is selected.
* When scrolling past end-of-file or before beginning-of-file,

* Make -w/-W highlight lines when moving backward as well as forward

* Allow ' command to take a numeric argument to specify the screen

* Support POSIX character classes with the built-in V8 regex library
(github #732).
* Change | command to pipe just one line if the marked line is at the
top of the screen (github #733).
* If OSC8 opener command begins with "-", suppress command echo,
and if it begins with ctrl-P, suppress "done" message (github #747).
* Don't ask for confirmation when input is a binary file and stdout is
redirected. Fixes infinite loop in that situation (github #719).
* Make early error messages go to stderr if stdout is redirected
(github #719).
* Don't retry read after read error; fixes hang when attempting to read
a directory or other unreadable file (github #741).
* Fix incorrect restoration of saved mark if not at top of screen.
* With --save-marks, don't save a mark that was cleared with ESC-m.
* Fix buffer overflow when using malformed lesskey file (github #721).
* Fix unexpected scrolling past end of file (github #720).
* Fix bug when env var in LESSKEY_CONTENT partially matches env var
defined in lesskey file (github #727).

to scroll to end of file (github #658).
* Configure tty to leave CR and NL unmodified (github #703).
* Add commands to lesskey parser (forw-bell-hilite, goto-pos and osc8-jump).

Add shift-HOME and ctrl-HOME to scroll left and jump to top, and
add shift-END and ctrl-END to scroll right and jump to end (github #658).

* When setting line number colors (-DN), don't force bold attribute.
To set bold, you must append "d" or "*" to the color string (github #684).

This reverts to behavior that existed before less-670 (github #700).

(github #662).
