Occur/Multi-occur looks great and igrep was just an old version :-) I always
had problems to find the newest packages; it looks like that
emacswiki has some of the newest ones...

One question to multi-occur, right now it displays the
matching lines for the given regexp for the chosen files, which is
fine, but am I able to run some kine of ediff so multi-occur
highlights the different listed lines, e.g.:

  20 matches for "inlet" in buffer: *Occur*<2>
   35:       inletvelocity = 10 [m/s]
   38:       inlet = 2
  9 matches for "inlet" in buffer: keps_small_301.out
   36:       inletvelocity = 20 [m/s]
   40:       inlet = 2

So it would highlight the lines containing 'inletvelocity'!?
