Word wrapping in Tweak

What's the story with MultiCompositionScanner? The version I have in  
my (not too recently updated) Tweak image is used by CTextComposer as  
the scanner, and is the reason word wrapping seems broken in Tweak.

I regressed to CompositionScanner, which got word wrapping back at  
the cost of multi-lingual compatibility (?).

I was just wondering if MultiCompositionScanner had progressed beyond  
12/2002 (timestamps seen in there).

We fixed this a long time ago. If you look at
MultiCharacterScanner>>scanCharactersFrom:to:in:rightX:stopConditions:kern:
this method should be from '05 with the main difference being that the
(broken) call to basicScanCharacters... is taken out.

But word wrapping is still occurring in the middle of words in my image.

I found differences between MultiCompositionScanner and  
CompositionScanner in crossedX, notably that breakAtSpace is set to  
false in setFont, causing crossedX to drop to the clause at the  
bottom commented:

"It wasn't a space, but anyway this is where we break the line."

So, as shipped the class will always break the line anywhere. But  
setting breakAtSpace true did not seem to fix to problem. Also, i  
tried initializing MultiCharacterScanner:

(MultiCharacterScanner(class)>>initialize

with no effect. I can see the wrapping being broken in the first two  
windows you open when Tweak starts up as downloaded straight off impara.
