i'd say the reasoning was perfectly obvious:

maximize the number of viable machines!

_can't_wrap_ + _can_wrap_ > _can_wrap_


by the way, here's an online unwrapper:

this version has the requirement that
a space in the first column of any line
means the linebreak preceding that line
was significant, and is not to be deleted.

oh, and by the way, if you wanna wrap,
counting characters is an archaic way...

better to assign a "standard" font --
e.g., like times roman or helvetica --
and then chop lines by stringwidth...

and you don't need to write a routine
to do that...  run out a .pdf, then save
the text with the "export" command...
