which version of "[" does support this? Mine doesn't.

I'd prefer the 99video hook to be self contained (what happens if a user
renames 99video to 98video?)
Just make the whole hook exit before checking for suspend or resume if there
is nothing to do.
Running a hook that does nothing else then disabling another one immediately
brings back RFC1925 - "you can always add another level of indirection" ;-)
Have fun,
Stefan
