I see.

Yes. That's why I hinted at --wordchars thinking it might be an option 
to make it configurable. Anyway, I do understand that it's not as 
trivial as I was hoping.

I've never done much coding in C, but my brain tricked me into 
believing you wrote it was "simple" to make a patch, and so I gave it 
a try :) I only added ']' as another character where nano can 
softwrap. The source compiled and nano wraps. So, I am happy and will 
test this.
