[doc] Enable Warning 50 [incorrect doc comment] and fix comments.

This is a pre-requisite to use automated formatting tools such as
`ocamlformat`, also, there were quite a few places where the comments
had basically no effect, thus it was confusing for the developer.

p.s: Reading some comments was a lot of fun :)
