length of staff lines in score with only spacer notes

[Reinhold Kainhofer]

If I have a score containing only an s8 spacer rest, the staff lines will 
always have the same length, no matter how wide the key/clef/time signatures 
are. As a consequence, in some cases the staff lines are way too short (leaving 
to the time signature without staff lines) and in some cases they are too long. 
Attached is an example. 
Any idea where the problem is and how it might be fixed?

The other problem appears with the key signature, when you remove the 
Clef_engraver (because sometimes you only want to print the original key 
signature in an incipit of a critical edition): The key signature has no 
padding on the left, so it starts even a little bit before the staff lines...

That case is also included in the example.

Any ideas how these issues can be fixed?

Cheers,
Reinhold
