abbreviated-home-dir is essentially a cache used by
abbreviate-file-name, and when the value of HOME is changed the cached
value is wrong, hence why setting it to nil is the right thing.
Possibly we should record the value of HOME we cached and clear it
automatically when a new one is used so that this kind of thing is not

Maybe the set-window-buffer from the other tests leaks in? For some
reason I can't reproduce this today, every time I run with the
set-window-buffer commented out it consistently fails. I'm sure
yesterday I saw it succeeding after the first time.

I mean "coincidence" in the same way that the 5th digit of pi being 5
is a "coincidence" (slightly less reliable than that though,
presumably if we made `initial-scratch-message' long enough the batch
mode behaviour would change).
