[pmwiki-users] title directive does not affect the whole title?

[Stephan Schildberg]

When I want to change the title of:
http://www.pmwiki.org/wiki/Main/WikiSandbox

I insert:
(:title example:)

with this result:
PmWiki | Main / test

....but I want to change it to:
PmWiki | example

I may either have missed a important part of the discussion going on or 
I did not found the adequate documentation for it.
Could you point me to the fitting description please?

regards, Stephan.
