(This is a bit out of context, but I didn't want to open an extra thread):
This refers to Alfred Werner's suggestion 'Four messages to merge?' in the Bugtracker:

Please be very careful about this. It might make sense - or not. You can only find this out if you know the precise context of the phrase in the UI (and comparable other phrases... e.g. Is it a heading? How are other headings structured? etc.). Simply searching for redundant messages in the listings and merging them is dangerous.
