And no, this can't be a mercurial patch, because the luarocks infra
downloads archives from the lua package repositrory, which are
organised quite differently from the source tree.

So, the patch we carry is different from (really, a superset of) the
patch that I sent upstream:
    https://bitbucket.org/doub/flu/pull-requests/1

So, no, we won't carry a mercurial-formatted patch, I'm afraid... :-(

Yann E. MORIN.
