I think the only problem preventing this change is one completion message
that overwrites the minibuffer when TAB doesn't find a completion.
I propose the patch below similar to the patch I proposed for the
shell command minibuffer completion.
When this is fixed, it makes sense to allow TAB to complete a lisp
symbol part of the eval-expression minibuffer in the same way as TAB
will allow completion of command name and file name parts of the
shell-command minibuffer.
