This is handled by the DISKDEF macro; one of the values you hand to it
when defining a disk format is the number of directory entries. It's
pretty arbitrary, but much like configuring the number of inodes in
older UNIX filesystems, one can strike a good balance. It's (usually!)
silly to have 255 directory entries, for example, on a 180KB disk format.
