Keep punctuation with words on soft-wrap

[notpeter]

Summary

In certain cases soft-wrap may wrap punctuation separately from the word that it follows. For example Boo! should never become Boo\n!.

Description

Steps to reproduce:

1. Paste this into a zed buffer

   No forking of an editor required!
   

2. Enable soft-wrap
3. Resize the window until the exclamation point wraps.

Expected Behavior: required! is on one line or the other
Actual Behavior: required! can be split across two lines as required and !
