Fix possible use after free with long lines Files with very long lines on machines with tight memory restrictions can provoke a failing realloc in expand_linebuf. This error condition was improperly handled, which could lead to a user after free bug by using the already freed linebuf variable again. with input by and okay guenther@

less uses a correct raceless signal method of indicating signal events in a volatile sig_atomic_t variable, and then processing events in the mainloop. But only one variable was used for 3 signals, with |= bit operations which are signal interruptable! Rewrite the code to use 3 independent variables and cleanup how the mainloop observes indications. ok schwarze

UTF-8 cleanup in the function pshift(). Use the standard functions mbtowc(3), wcwidth(3), iscntrl(3) instead of bad functions like get_wchar(), utf_len(), is_wide_char(), is_composing_char(), is_combining_char(), control_char(). If only half of a double-width character is shifted off screen, do not inspect anything following it because that clearly remains on-screen. Improve and add comments. OK millert@

Clean up UTF-8 handling in backc(): Use wchar_t instead of LWCHAR and mbtowc(3) instead of step_char(). Play it safe and handle all error cases, even in the arguably unlikely case that linebuf[] contains UTF-8 encoding errors. Reset mbtowc(3) internal state after failure for portability, also in one place where mbtowc(3) was already introduced earlier. OK nicm@

Start UTF-8 cleanup of store_char(), in particular getting rid of a call to the flawed function step_char(-1), using the standard function mbtowc(3) instead.

To simplify the upcoming UTF-8 cleanup in less(1), delete support 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.

To measure the display width of a wide character in pwidth(), use the standard function wcwidth(3) instead of several hand-rolled functions accessing outdated local character tables, making this part of the code conform to our in-tree Unicode 10. Of course, with the current hand-rolled (and buggy) UTF-8 parser contained in less(1), this only works if wchar_t stores UCS-4 values and is more than 31 bits wide, but both will always be true on OpenBSD, and ultmately, we shall switch to mbtowc(3) for parsing anyway, lifting these restrictuons. The existence of the outdated character tables was originally called out by Evan Silberman on bugs@. OK stsp@

Improve handling of ambiguous overstrike sequences. A sequence of _\b_ can either mean an underlined underscore or a bold underscore. This ambiguity can be 'resolved' by takeing the state of the surrounding text into account. If surrounded by bold text, the result should probably be bold and likewise for underlined. less(1) previously only looked at the preceding text and ul(1) didn't examine the context at all. tweaks and ok schwarze ok tb (on a previous version of the diff)

Replace less with the cleaned-up fork of less 458 maintained by Garrett 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.
