slur slope question

[Karol Majewski]

Please, take a look at the attachment. This is excerpt from one the old Henle 
Verlag editions. Although slur goes from bes to bes, it is sloped - because of 
staccato. And it looks absolutely fine.

Now, look how LilyPond handles this:

{
 bes8 ( d'16 c'16 bes4 -. )
}

Here, there is this gap between first note head and slur start point, which 
doesn't look good. Of course I know that I can tweak this via \offsetPositions 
(http://lsr.di.unimi.it/LSR/Item?id=748). But the question is: can I change 
this behavior in more general way? For example by overriding one of Slur.detail 
parameters?
