fix for incorrect (partial) written sequences when libc wcwidth() == -1
Fix an issue with incorrect (partial) written sequences when libc wcwidth() ==
-1. The sequence is updated to on wcwidth(u) == -1:
c = "\357\277\275"
but len isn't.
A way to reproduce in practise:
* st -o dump.txt
* In the terminal: printf '\xcd\xb8'
- This is codepoint 888, on OpenBSD it reports wcwidth() == -1.
- Quit the terminal.
- Look in dump.txt (partial written sequence of "UTF_INVALID").
This was introduced in:
" commit 11625c7166
Author: czarkoff@gmail.com <czarkoff@gmail.com>
Date: Tue Oct 28 12:55:28 2014 +0100
Replace character with U+FFFD if wcwidth() is -1
Helpful when new Unicode codepoints are not recognized by libc."
Change:
Remove setting the sequence. If this happens to break something, another
solution could be setting len = 3 for the sequence.

Similar to [dwm-flexipatch](https://github.com/bakkeby/dwm-flexipatch) this st 0.8.3 (df79f2, 2020-05-09) project has a different take on st patching. It uses preprocessor directives to decide whether or not to include a patch during build time. Essentially this means that this build, for better or worse, contains both the patched _and_ the original code. The aim being that you can select which patches to include and the build will contain that code and nothing more.

For example to include the `alpha` patch then you would only need to flip this setting from 0 to 1 in [patches.h](https://github.com/bakkeby/st-flexipatch/blob/master/patches.def.h):
