References in doc strings

[dbuenzli]

are not hyperlinked and references to identifiers not wrapped in a code tag.

Contrast the links in the preamble of this module:

http://docs.mirage.io/odoc/astring/Astring/index.html
http://docs.mirage.io/astring/Astring.html

Contrast the doc string of the two first values in the String section here:

http://docs.mirage.io/odoc/astring/Astring/index.html
http://docs.mirage.io/astring/Astring.html

The first part of the issue is that odoc doesn't handle "forward references" correctly, this is blocked on @lpw25 rewrite of parts of doc-ock.

The second part (the doc string being incorrect) I will fix today.

I misread the odoc file, the reference is resolved and the problem is indeed in doc-ock-html, I will fix this.
