1. Document CONTROL MODE (and the fact that you can do I/O now if
the device is opened in control mode- the actual close behaviour
is akin to normal mode (i.e., it rewinds)). This should probably
either be a separate bit, or O_NDELAY on the open as well.
2. Document new MTEWARN subcommand to MTIOCTOP (enable/disable
early warning behaviour).
3. Document EOM handling more fully.
4. Note that for DENSITY and BLOCKSIZE values that the values you
set aren't persistent past the current mount session unless you have
the CONTROL MODE device opened.
5. Remove the old EOM handling BUG notice and instead note that having
a minor bit for compression selection wouldn't be a bad thing.
Flame on!
