keywords in the middle of messages get stripped

Sometimes, a user of a schleuder list might send instructions about how to control a schleuder list in a message that went to the list itself. If the instructions include keywords, those keywords are stripped before re-sending, even if those keywords are not at the top of the message. Using schleuder 4.0.3-7 (as packaged in debian stable, version 12.5), i sent the following message to a schleuder list: ``` Please ignore this message, i am trying to debug a possible schleuder bug. Here is a schleuder keyword command in the middle of the message text: X-LIST-NAME: foo@example.org X-ATTACH-LIST-KEY: -----BEGIN PGP PUBLIC KEY BLOCK----- nothing to see here. And here is some followup text. --dkg ``` The signed, encrypted version of the message that came back from the list had the expected spliced metadata part: ``` From: Daniel Kahn Gillmor To: [REDACTED SCHLEUDER LIST ADDRESS] Cc: Date: Mon, 11 Mar 2024 15:08:50 -0400 Sig: Good signature from BB7E9101495E6BF7 Daniel Kahn Gillmor Enc: Encrypted ------------------------------------------------------------------------------ ``` and the rest of the body said: ``` Please ignore this message, i am trying to debug a possible schleuder bug. Here is a schleuder keyword command in the middle of the message text: nothing to see here. And here is some followup text. --dkg ``` It seems to me that keywords that are not at the beginning of the message should be ignored, not stripped.
