Hi Ævar, the commit title is misleading: it suggests that there is a bug that needs to be fixed. The idea of the patch, however, is to avoid redundant code, and if described that way, the patch is a lot better for it.

The diff does too many things, some of which are your purely personal preferences and do not actually need to be changed.
