[PATCH 07/16] qapi: Improve error message for empty doc sections
Posted by Markus Armbruster 8 months, 2 weeks ago
Improve the message for an empty tagged section from

    empty doc section 'Note'

to

    text required after 'Note:'

and the message for an empty argument or feature description from

    empty doc section 'foo'

to

    text required after '@foo:'

Improve the error position to refer to the beginning of the empty
section instead of its end.
