Renamed and copies not shown on commit page

In a Mercurial repository, you cannot see if a file was renamed (hg rename) or if the old name was deleted and the new added (hg add; hg remove). It is as if Bitbucket runs Mercurial with diff.git = true in the config file.

An example of a rename is 8fb8dce3f9b6 in Mercurial's repository. The test-config-case.t file was renamed to test-config.t, but this cannot be seen. This makes it practically impossible to review changesets involving renames.

Running hg serve --config diff.git=true shows how one can do it instead by adding "rename from tests/test-config-case.t" and "rename to tests/test-config.t" lines above the diff. I'm sure you can come up with something nice here

For copies, it is only the new file that shows up in the diff on Bitbucket, as seen for 5c5152af0d15 where map-cmdline.phases was copied from map-cmdline.defaults.
