Patchset 5 warns the user when the extent is empty and stencil isn't. However, i'm not sure if we should warn about such situations at all; i haven't found any similar warnings in the codebase. Also, detecting non-empty stencils with empty extents is quite unrelated to alignment code.
Please choose between patchsets 4 and 5.
I prefer 5. The warning does no harm if it is never triggered, but is there in case some future change elsewhere assumes a non-empty stencil will be aligned even if its extent is empty. It is relevant to these alignment routines as they cannot calculate the offset required to achieve the specified alignment of such grobs, so should warn if a caller appears to be expecting them to do that.
