. avoid resetting the FDC every time the last motor is going off;
instead, give it a 60-second period for possible later reactivation.
This prevents us from needing to recalibrate the FDC too often,
but still allows for an ``automagic error recovery', just in case the
controller is absolutely stuck. (Simply wait for 60 seconds, and
try it again.)
. made the floppy head settle time after a seek a constant
that might be overridden by a config option. (Well, actually the
divisor of the settle time). Pepople often reported problems with
their floppies, so i need a simply mechanism that allows them
to play with that value. (I personally cannot find any problem
on *my* drives.)
. implement the FD_DEBUG ioctl command, in case the driver
is compiled with DEBUG turned on.
. removed a bogus parameter from a printf; the remaining warnings
from gcc -Wall seem to be warnings about the %b format gcc cannot
understand
. rearrange Garett's code to fit better in the existing structure
of #define/type/function ordering.
. make everything fit into 79 columns again.
