This is what happens for me:

$ git clone https://bitbucket.org/eschnett/carpet.git

Does this mean we would require clang-format-3.6 (and not supporting
3.5 or earlier)? I thought clang-format wouldn't change the way it
formats stuff in between versions, but it apparently does. One example
from the current changes:

-vector<vector<int> > const &HostProcs() { return host_procs; }
+vector<vector<int>> const &HostProcs() { return host_procs; }
