This morning's sup is generating a lot of extra old directories (with no
contents), such as

SUP Created directory src/distrib/i386/floppies/upgr
SUP Created directory src/distrib/i386/floppies/kcoth
SUP Created directory src/distrib/i386/floppies/kcbt
SUP Created directory src/distrib/i386/floppies/kcaha
SUP Created directory src/distrib/i386/floppies/kcadp
SUP Created directory src/distrib/i386/floppies/kc-common
SUP Created directory src/distrib/i386/floppies/kc
SUP Created directory src/distrib/i386/floppies/inst-common
SUP Created directory src/distrib/i386/floppies/inst

It also included some directories which exist only on branches, such as

SUP Created directory src/sys/dev/scsipi
SUP Created directory src/sys/dev/pcmcia

What's going on here?
