M->S messages get the first newline eaten

[auscompgeek]

If I send a multiline Matrix message, the bridged message on Slack is missing the first newline in the message. If there are multiple newlines, only the first disappears.

I can't reproduce this but sending a message with only a single line break ends up stripping that line break.

oh I can repro this, I misread the bug.

I'm not sure if this is related, but no newlines in slack go through to matrix:

{
  "content": {
    "body": "1\n2\n3",
    "format": "org.matrix.custom.html",
    "formatted_body": "1\n2\n3",
    "msgtype": "m.text"
  },
  "origin_server_ts": ,
  "sender": "@_slack_...",
  "type": "m.room.message",
  "unsigned": {
    "age": 268
  },
  "event_id": "",
  "room_id": ""
}

But everything is on the same line in matrix.

When I send from matrix it of course shows up properly, the message source doesn't look that different. It's \n in both.

{
  "content": {
    "body": "1\n2\n3",
    "msgtype": "m.text"
  },
  "origin_server_ts": ,
  "sender": "@Stephen304:matrix.org",
  "type": "m.room.message",
  "unsigned": {
    "age": 200,
    "transaction_id": ""
  },
  "event_id": "",
  "room_id": ""
}

That's #547.
