My original problem I solved by putting an explicit (raise-frame) after the
(find-file \"foo\")

Now the new problem is that that mode-line in this case is really ugly: the 
entire command arbitrarily truncated.

Now I guess I could tweak that but somehow its all smelling wrong.

Your point:

> That behavior is no different than if you did:
> $ emacs foo
> is it? 

is technically valid but it seems (to me!) to miss the point that emacsclient 
is used in different circumstances than emacs, viz when some process wants to
hand-off some stuff to 'whatever is $EDITOR'

Anyhow let me just take what you are saying and rephrase my question:

How to programmatically (ie in elisp) visit a file with a specific mode?
say a .c file in text mode

Note 1. I wish to avoid having to issue any M-x commands
Note 2. I have no control over the file -- so no file-variables possible
Note 3. This is odd-case behavior ie we dont want to modify default behavior(s)
ie no auto-mode-alist changes

So, poking around I see that 'after-find-file' and 'find-file-hook' is 
closest to what I want... but now the mode-line is a mess.
