docs/devel/qapi-code-gen.txt claims "A heading line must be the first
line of the documentation comment block" since commit
55ec69f8b1 (docs/devel/qapi-code-gen.txt: Update to new rST backend
conventions). Not true, we have code to make it work anywhere in a
free-form doc comment: commit dcdc07a97c (qapi: Make section headings
start a new doc comment block).
Make it true, for simplicity's sake.
