+The 'remotefilelog' capability should *not* be exported over http(s),
+as the getfile method it offers doesn't work with http.

+Verify serving from a shallow clone doesn't allow for remotefile
+fetches. This also serves to test the error handling for our batchable
+getfile RPC.

+This GET should work, because this server is serving master, which is
+a full clone.

+
+This GET should fail using the in-band signalling mechanism, because
+it's not a full clone. Note that it's also plausible for servers to
+refuse to serve file contents for other reasons, like the file
+contents not being visible to the current user.
