I want to suppress several types of messages in the game entirely, using the appropriate section in adom.msg file.
Notably, all the shopkeeper related messages, for all shopkeepers of all races for all time.
However, adom.msg doesn't seem to work, no matter how I define the lines to suppress.
Also, ToEF messages are likewise included in the suppression list but they too consistently appear in the game.

Forget the wildcards for a moment (%s or %d or whatever).
I tried to suppress the messages with exact wording for a specific game, like this:

Barnabas, the trollish shopkeeper, mumbles: "I saw dat!"

Nevertheless it still appears.

I disabled sage since I was worried it might interfere with adom's built-in suppression system but no.
With or without sage - adom.msg message suppression system doesn't work in the case I described.

Any idea? Something I'm doing wrong? Any detailed guideline about wildcards and line breaks that seem to be often implemented?
