-----------
reflow: Don't split right before a whitespace

Avoid splitting lines right before a whitespace when reflowing (e.g.
in case of several consecutive ones) not to move whitespaces at the
start of the next line, which, while they will be removed later on,
can lead to incorrect reflow width and even fully empty lines.
Prefer leave trailing spaces then, which is less of a problem.
