Changes:
0.8.4
=====
Security
--------
* config.def.h: add an option allowwindowops, by default off (secure).
Similar to the xterm AllowWindowOps option.
The sequence for base64-encoded clipboard copy is now guarded and off by
default because it allows a sequence written to the terminal to manipulate the
clipboard of the (other) running user non-interactively.
Features
--------
* Integrate auto-sync: draw on idle to avoid flicker/tearing by avih.
st could easily tear/flicker with animation or other unattended
output. This commit eliminates most of the tear/flicker.
* Optimize column width calculation and UTF-8 encode for the common-case ASCII.
In particular on glibc and OpenBSD the wcwidth() call is more expensive.
On musl there is no/little difference.
* Add support for REP (repeat) escape sequence and xterm compatibility, by
avih. The capability is not exposed yet due to some issues with
applications.
* Call xsetcursor to set win.cursor in main, by Steve Ward.
Allowing to set the st snowman cursor extension dynamically.
Fixes and other changes
-----------------------
* Fix unicode glitch in DCS strings, by Tim Allen.
The related sixel stub code is now removed also.
* Fix for incorrect (partial) written sequences when libc wcwidth() == -1
and using st -o.
* Mouse selection fixes, by Jakub
* Make shift+wheel behaves as shift+Prev/Next, patch by k0ga
This patch adds a new hack, making shift+wheel returning the
same sequences than shift+Prev/Next, meaning that scroll or
any other similar program will not be able to differentiate
between them.
* Expose rin terminfo capability.
Tianlin Qu discovered that st is missing rin (scroll back #1 lines).
* Replace exit(3) by _exit(2) in signal handler sigchld(), by Jan.
This change prevents st to crash and dump core in some situations.
* FAQ: add details and a patch example for single-buffering (for the w3mimg
hack).
