[XeTeX] polyglossia, babel and French hyphenation

[Cyril Niklaus]

Hello,

Thank you for your replies indicating the hyphenation limit on left  
and right letters.
As I suspected, my lack of skill and knowledge was to blame here.

Indeed it does, but as you point out it does not solve that  
particuliar problem.

Without changing the text nor the margins, that leaves the spaces  
between the words and between the letters, right? Off to my LaTeX  
books to see how to modify that manually! (references welcome, of  
course)

In this particuliar case, using \sloppy for that passage and then  
going back to \fussy doesn't change the line. So still had to manually  
hyphenate it.

Nevertheless, both suggestions were helpfull, for which I'm grateful.
