Thanks for the comments; if this is intentional behaviour then everything is 
working correctly.  I didn't like this happening myself and so looked for a 
way to customise it, and couldn't find one at the Lisp level - but then most 
of my elisp experience has been with XEmacs which didn't support eval forms 
within f-t-f.  Following your suggestion, though, I've found a way that works 
and doesn't need any Emacs changes.

Since there is a way around it, I'll agree.
