QDoc gets confused about the contents of doc_src_plugins.qdoc,
mistaking some of its code for QDoc commands.
To work around this problem, change the file to be a qdoc
include file, wrap the code blocks with \badcode, and
refer to them using \include.
Using \badcode will also turn off code highlighting and
autolinking, something that is not desired for these code
snippets.
