REST API: List all files in repo (like git ls-files) (BB-9449)

There is a "manifest" REST API endpoint for this that is undocumented and seemingly broken. I found it via the apigee browser:

curl https://bitbucket.org/api/1.0/repositories/aslakhellesoy/pygments-main/manifest/a32d7988c3695e0b0a41cf764afaa9e701a858e7

(The apigee API browser suggests a trailing slash, which didn't work).

Anyway, this will only list the files at the root of the repository. I don't know if it's possible to make it behave recursively.

Is there another way to list all files in a repo (for a given revision)? We'd very much like to support Bitbucket in https://cucumber.pro, but we need this functionality to do so.
