@hund neomutt does not group URLs at the bottom of the msg, at least not my version. It shows the raw text mostly as-is. I think your 1st example is probably a msg with text/html MIME type that mutt filtered with w3m or the like. When mutt shows an URL, it's often so long that mutt wraps it and adds a "+" where the link wraps which ruins copy-paste. Urlview/urlscan fixes that.
