prohibiting Gnus from striping `(...)' in summary buffer

[Patrick Drechsler]

Hi,

is there a way to refrain Gnus from deleting `(...)' in the
summary buffer for certain groups only? 

Normally this indicates a change of subject so striping that part
is OK. But some of my lists include the date of the message (or
other relevant information) in the subject as in:

I couldn't find anything in the manual -- probably using the
wrong keywords for searching...

Thankful for any pointers
