I've got a changeset in code review to make the default redirect resolution
behavior of action=opensearch consistent between JSON and XML-mode requests.
Originally the JSON version did not resolve redirects as it was easier to
implement that way, while the XML implementation was separately written and
did resolution in order to improve display of content snippets. Content
snippets are now included in JSON as well as XML since the implementations
were merged, and in general it seems to be better behavior to be consistent
across data formats for the same requests.
The original behavior can be obtained by supplying an explicit
'redirects=return' parameter to the API request.
Are there any compatibility worries here?
