Well, I'm still not really an expert, but as I'm beginning to  
understand more and more, what you altered was the base Knuth element  
generation, right?

IIUC, a possible solution may be to treat SHY as special *only* if  
hyphenation is turned off.
The reasoning being that, if hyphenate is true, then handling the SHY  
becomes the hyphenator's job. The SHY character will be presented to  
the hyphenator simply as a character of the word it appears in. The  
hyphenator should then be smart enough to recognize this as a special  
character, and do something like: create a hyphenation point for the  
SHY, and try to hyphenate the parts before and after the SHY as  
separate words...
