Hi all,

attached is a patch that enhances org-babel-goto-named-src-block (bound
to C-c C-v g by default).  Included are two enhancements:

 1. the point is pushed to the org-mark-ring, such that returning with
    C-c & becomes possible
 2. the target src block is guessed from
     a) noweb-reference
     b) #+call:
     c) #+results:
     d) symbol-at-point
    if one of these is found (in that order)
