Give the demo disk room for names, not just for bytes

The demo disk had eight directory blocks, which is sixty four names, and
thirty nine of them were already spoken for. Its two ceilings were nowhere
near each other: the average file on it is twenty six blocks, so sixty four
names run out with the disk forty one per cent full. Names were going to be
gone long before space was, and space is what a disk is usually short of.

Twenty four blocks is one hundred and ninety two names. The difference costs
sixteen blocks of four thousand and ninety six, three tenths of one per cent,
and the superblock has carried this number per disk since the format was
written - so nothing but the makefile line knows or cares what it is.

This is provisioning and not format. Directories, when they arrive, will not
relieve this pressure; under the settled design they add to it, because a
directory spends an entry of its own.
