Update strsetp(3) EXAMPLE section.

[araujo]

Summary

As many people has pointed out, using assert(3) shall be not the best
approach to verify if strdup(3) has allocated memory to string.

So, I'm updating this manpage example section.

Thanks for doing this...

Others in the tree if you feel inclined, otherwise a bug might be in order so we don't lose it.

Hi,

Yes, I'm inclined to do this clean up and we all can avoid confusion in the future.

Thanks,

You can't free string. If doesn't point to something allocated by malloc() (unless you'd strdup'd "" in which case it would be a double-free bug.
