The first one is complicated and would tie auth-source.el tightly with
the rest of Gnus (which I'm trying to avoid because autoloading
`auth-source-search' should work outside of Gnus).

I pushed in a change to use `save-excursion' and `delete-window' because
all the other setups seemed too complicated.  But if it's not working
right, please let me know.

I also think that maybe I want something other than read-char.  It
errors out if I hit a cursor key, for instance.  What would be a good
function to use that supports prompts in XEmacs?  `read-key'?
`read-char-exclusive'?

Thanks!
