We had some pretty lengthy discussion today with Peter and Yann about
this patch, arguing about the various possibilities to solve this
problem. In the end, even though your solution is a bit of a hack, it's
the one that is the easiest in terms of on-going maintenance, so I
applied your patch after doing some minor modifications:

    [Thomas:
     - rename the loop variable from 'D' to 'patchdir'
     - add some additional comments
     - remove final ; at end of loop when applying the patches, since it's
       not needed]

Thanks!

Thomas
