draw565: Avoid over-long lines when handling space

Browse source 
Currently, if the line wrapper attempts to break a line on a space and
that space character is outside the bounding box, then we generate an
over-long line.

Fix this by handling line break generation *after* we have checked the
length of the current line.

Fixes: #193
