After thinking a bit more about this, IMO these backup and autosaved files 
can be kept by the new bootstrap-clean, given that it seems unlikely that 
these files have an effect on the build, or at least that it is not more 
likely that they could impact the build more than user-created files 
(which aren't deleted by extraclean either).
