This has to do with hanging hyphen implementation.
You want hyphenation at a point where there is a `normal'
hyphen already to use the hanging hyphen.
The hanging hyphen has half the advance width of the true hyphen
(but has the same shape):
C 45 ; WX 333.252 ; N hyphen ; B 0 0 303.252 430.45 ; L hyphen endash ; L sfthyphen sfthyphen ;
C 127 ; WX 166.626 ; N sfthyphen ; B 0 0 136.626 430.45 ;
