Ok, solved my own problem, but I have no idea how, so if anyone has any
insights I'd still love to hear them.

From the behaviour I was seeing (described below) I had decided that
perhaps there was something wrong with the smb.conf file, which I had
mostly copied over from another machine. So, in desperation, I
commented out every single line in the file, and added back the most
basic configuration options until I could connect to the samba share
with smbclient. Then, to discover what was causing my problem, I added
back the other commented lines one at a time to see which one broke it.
Well, in the end I added them all back, and it still works! So, in
short, the solution to my problem was to comment and then uncomment the
smb.conf file?!? I just ran testparm again and the output is exactly
the same as the one from yesterday quoted below. Nothing else on the
machine (should have) changed.

I think my machine is haunted... *sigh*
