Remove newline to fix list rendering

[tcharding]

Currently the newline in list items in BIP-0158 is causing the text on the new line to be rendered as a code section. I am unsure why this is happening but putting all the text for each list item on a single line fixes it.

Verified that the display issue exists and that the patch fixes rendering. I tested removing the whitespace after the newline but preserving the newline itself to see if that helped but it did not, so the suggested solution seems reasonable to me.

Minor nit if you're up for ACKing, @Roasbeef and/or @aakselrod

Friendly bump - I went to read the BIP again today, saw the issue, went to fix it, and realized I fixed it years ago :)

This looks good to me. :+1:
