Hiltjo Posthuma 8211e36d28 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.

README

st - simple terminal
--------------------
st is a simple terminal emulator for X which sucks less.


Requirements
------------
In order to build st you need the Xlib header files.


Installation
------------
Edit config.mk to match your local setup (st is installed into
the /usr/local namespace by default).

Afterwards enter the following command to build and install st (if
necessary as root):

    make clean install


Running st
----------
If you did not install st with make clean install, you must compile
the st terminfo entry with the following command:

    tic -sx st.info

See the man page for additional details.
