Hi,
nevermind. I figured out that the expansion order of %s and s
expressions is the problem and also the reason for the with the
correct URL.
The solution is to use %(get-page-title (current-kill 0)).
Can this be added to the documentation or is it supposed to be obvious
from the order of available template expansions?

Philipp
