That did it!  Now I can login as nonroot and startx.

I found pwd_mkdb in my searching, but would not have known to use '-p'.  I might have done

pwd_mkdb /etc/master.passwd

That seems like a good idea, using -P option to be able to go back to something good if one screws up.

>From 'man mergemaster':

     The mergemaster utility is a Bourne shell script which is designed to aid
     you in updating the various configuration and other files associated with
     FreeBSD.  It is HIGHLY recommended that you back up your /etc directory
     before beginning this process.

So I could make a second backup of /etc before the second mergemaster invocation, after installworld.

There are lots of files to merge/edit, and one can easily become tired and make mistakes.  We're only human and not infallible.
