Is that the XREF buffer?  Or is that the buffer where the definition
was shown?

I don't understand why you call them "temporary": they are normal
buffers visiting files that belong to the program you are working on,
right?  And if you care so much about what goes into your desktop
file, then you review the list of buffers each time before ending a
session, right?

Anyway, I don't want to argue about this.
