Simply because it's not good to leave something 93% done
(compared to, say, 100% or 40%, which are both good exit points,
or even 99%). :)
This may also have to do with schooling. Just because
your classmate has done the homework assignment doesn't
mean you don't have to. :)
Before I started, I looked in the mailing list
and GIT, but I didn't find the new script, unfortunately.
This is something I need right away.
I just took an extra few minutes to put in the link-breaking ``noop''.
Breaking hard links is done easily using an in-place sed (sed -i):
find "$opt_prefix" -type f -links +1 | xargs sed -i -s ''
I'm happy with the way it works now, so I can leave it alone!
