So like I just changed it?

I considered making this PR mostly because dalias said he agrees with the design, so I didn't expect any huge issues with the impl. Might not be the most optimal, though.

Are your issues more with the idea of having `_FORTIFY_SOURCE` functional on musl, but requiring more bounds checks and binary size than it used to, or with the fact that this lib isn't as well implemented as it could be?
