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 11625c7166b7e4dad414606227acec2de1c36464

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.
