Re: Line wrap reconsidered

[Yuan Fu]

I had some problem hacking the redisplay code. For some reason, Emacs hangs 
after M-x toggle-word-wrap. I ran Emacs under lldb (gdb doesn’t work on Mac), 
and was dropped into different places each time. I attached the backtrace 
files. What could I did wrong?

Explanation for the code: basically I added a predicate function 
(char_can_wrap) that checks text property to see if a character is “wrappable”. 
And combined that predicate with the existing IT_DISPLAYING_WHITESPACE.
