I did, but I am new to Emacs customization and might have overlooked  
something.
If I do the equivalent of a

(setq grep-find-command "find somepath \\( -path \*/.svn \\) -prune -o  
-type f \\( -iname \\*.cpp \\) -exec grep -nH -e  {} /dev/null \\;")

in my .emacs file,
C-u C-u M-x rgrep
does indeed use this pattern (and does not ask about anything else,  
and I could use a keyboard shortcut for this) - so far so good.  
However, I feel that having to look at that long-ish command every  
time I use it, is not elegant - in particular, as I need to navigate  
to the correct position when the find command is being displayed in  
the minibuffer (point should be between "-e" and "{}" to insert the  
pattern to search for). Could you help me improve on this?

Many thanks in advance,
  Stefan
