Add missing coderef docs and fix syntax issues.
Review Request #9226 — Created Sept. 26, 2017 and submitted
Several modules have been introduced that haven't yet been added to the
code reference part of the documentation, preventing those modules from
being cross-referenced. This moves those modules and fixes a handful of
errors found in the codebase (including an obscure highlighting issue
with "whitespace" followed by a period).
Built the docs. No longer saw the errors. Verified that all the new
cross-references from the release notes worked.
