Oh, I forgot to mention why it is so. The directory is sent in
this mode just like any SEQ/PRG/USR file. After all, the link
in BAM block points to the first directory block and so on..

To remain (mostly) compatible, even the 1581 drive sends only
one block (header block, no BAM) before the actual directory
blocks.

And note to the filesystem discussion: yes, REL files are just
like SEQ/PRG/USR files except that there in indexing information
for random access. E.g. my c1581-handler can read REL files just
fine as sequential data.

Another point: bit 7 in the file type means "closed", but bit 6
means "locked". Although not widely known, this is a standard bit
also.
