Paragraph line breaking

Paragraph line breaking

[nico]

Hello,

I'm trying to tweak some parameters to avoid lines going into the margin  
when it contains long words. Using \setuptolerance[tolerant (or  
verytolerant)] helps much but sometimes it isn't enough.

My questions are:
- Using \filename doesn't hyphenate on backslash characters (which is  
interesting for Windows paths). Is is intended?
- Is there a macro or something like this that I could put before the  
maybe too long word so that it breaks the line if the word doesn't fit in  
the line?
- Is there a mechanism to define an arbitrary hyphenation pattern?
- What are the other parameters I could try to avoid an overlong line?  
Looking at the style.pdf file, i don't realy know what is pertinent for my  
purpose.

Thanks for any hint.

Regards,
BG
