Field information not rendered with custom html.mustache templates

[aschrijver]

When copying the html.mustache locally and without modification run it like this:

protoc --doc_out=html2.mustache,index.html:build/html schemas/*.proto

Then all field tables are entirely missing in the output.
You can see the output in this gist: https://gist.github.com/aschrijver/0a2fb12347362ced80c6c5443fa8f40e

Switching back to internal template.. everything works.

Versions:

• Ubuntu 16.04
• libprotoc 2.6.1
• protoc-gen-doc 0.9 (presumably, but protoc-gen-doc --version is not supported to confirm that)
