bug#567: word wrap

[David Reitter]

[-- Attachment #1: Type: text/plain, Size: 1967 bytes --]

Lines with whitespace at the end get wrapped too early.  It seems like  
the word boundary is not recognized correctly.

To reproduce, enable word-wrap, then add spaces to a not-yet-wrapped  
line (at its end).

I think in this case it would be best to simply wrap the spaces as if  
word-wrap wasn't enabled.

AFAICT, the current behavior is identical to what other editors with
word-wrap do.  The convention is that each screen line starts with a
non-whitespace character.
