Always prefer breaking at word boundaries

Browse Source 
An overlong word containing a hyphen could be broken anywhere, instead of after
the hyphen.

Example: compare the line breaking of

   aaaaa-aaaaa-aaaaa-aaaaa

with

   aaa aaaaa-aaaaa-aaaaa-aaaaa

(with a very narrow window)

This also improves Chinese text in some situations (#10299)
