I'll definitely look into this, thank you.
@ Janek: as you know we can't wait for inclusion in LilyPond, I'll at 
least incorporate it you know where ;-)
It's for the articulation in op. 3,1 ...

To sum up the discussion:
Am I right that:
- staccato dots are intendedly aligned more towards the stem by default 
when on the stem side
- other articulations aren't
- if there happens to be staccato and other articulations present at the 
same time
  (when on the stem side) you have an inconsistency.
- This inconsistency isn't a bug but just a problematic situation that 
has to be dealt with manually
?

So the issue report has to be either
- marked as invalid or
- changed to a feature request to incorporate David's workaround
?

Best
