I'd thought of it, actually specifying breakpoints not before/after 
characters but before/after sequences; you'd need something like ``you 
can break after a slash unless it is followed by another slash''. The 
problem is it's a little bit more work, and we're turning this help to 
Till into package writing :)

Some times ago, I have written a tentative file meant to find sequences 
of nodes somehow like regexps; it could be put to use here, if it were 
cleaned up, but it would be a bit of an overkill. Probably defining 
things here like ``remove penalty between pair of slashes'' (to be 
applied after penalties have been inserted) would be simpler, albeit 
quite ad hoc and unelegant.

Best,
Paul
