  (get_file_from_ra): Use the 'scratch_pool' parameter where possible.
  (apply_textdelta): Pass the local 'scratch_pool' to it. This change
    currently has no effect because the 'scratch_pool' variable used here is
    simply a copy of the 'b->pool' that was previously used here. But the
    other two callers of get_file_from_ra() are passing real scratch pools.
