Do not match code "words" that are part of a hyphenated
string of characters: e.g. `platform-browser-dynamic` should
not auto-link `browser`.
Do not match code "words" that correspond to pipe names
but are not preceded by a pipe `|` character. E.g. `package.json` should
not auto link `json` to the `JsonPipe`.

Parse all `<img>` tags, during doc-gen, and insert the width and height of
the sourceed image, if neither are already specified.
Warnings are reported if the `<img>` tag has no `src` attribute or the image
cannot be loaded.
The work is done in the `addImageDimensions` post-processor, which must be
configured with a `basePath` so that it knows where to find the images.
