regarding that odd problem with scp

I found out what it was ....

Just to remind, when I tried to use scp, I got an error message 
complaining about the PermitLocalCommand variable not being recognized, 
so that I could transfer nothing via scp.

Well, it's an artifact of doing a buildworld & installworld, but not 
doing a new kernel, and not even doing a reboot.  Once I did a new 
kernel and rebooted, the problem disappeared.  Glad about that, because 
the way that the problem presented, well, it was more than a little 
unusual, and responded to none of the normal things you do to 
troubleshoot ssh problems.

So, this problem (at least) is taken care of.  Back to my audio driver 
distractions.
