Doc: Links to unix references
Both fs.write
entries refered to pwrite(2): "See pwrite(2)." This reference should be a link since there is no other mention of pwrite, but it wasn't.
This broken link seems to have been there for a long time on the Node fs API but a Google search led to this page with the concerned part of the Node API and a live link to this pwrite entry.
I added these links to the doc.
