I had overridden it in the theme to improve the metadata generated
by it. Hugo has accepted the changes upstream so we can use theirs
now.
See: https://github.com/spf13/hugo/pull/2984
Hugo's current handling of dates in the opengraph partial needs
nome work to be more correct—for example: the usage of published
and updated times. This comes verbatim from the Hugo source tree.
See: tpl/template_embedded.go
This replaces the metadata that Hugo's own schema.html template had
been providing, but does so in JSON-LD notation rather than via the
use of <meta> tags (this is Google's currently recommended form of
specifying this markup). There are a few exceptions where I did not
follow the conventions used in Hugo's template, for example the use
of up to six images from a post's frontmatter, because Google's tool
only recognizes one image, as well as different logic for a post's
publish and modified dates (using enableGitInfo = true).
Using this new markup, Google's Structured Data Testing Tool is now
able to understand site metadata much better (before it was reading
none).
The implementation here is a mix of the elements and types from the
official Schema.org types—for example, Blog and BlogPosting—as well
as from Google's search documentation. Note that Google's docs are
geared towards AMP, where some metadata is required, while for non-
AMP pages the metadata is just recommended.
We will have to re-evaluate this in the future, for example to add
height and width information to image metadata.

* Add Vim modeline comments to all relevent template files.
* Add Vim modeline comments to a few other files.
* Move modeline comments inside the template definitions in list and single.
For some odd reason, putting them outside breaks the page generation.
* Use template comments for modeline comments in templates.
* Fix form 2 modelines.
Instead of writing my own logic for metadata and Twitter cards, I
should be using Hugo's own. This makes my theme code cleaner, but
means I have to adjust some of the configuration conventions that
I have been using. An added bonus is that my theme will work with
more sites now, as long as they are using Hugo's config conventions.
I had added Google Webmaster verify support but it got lost when I
was re-organizing the head meta stuff. I'm adding it back now plus
support for Bing and Yandex.
