Ah, thanks. This was added by:
commit 25449e7296fe6e5cd9bca49ae1bc52d1552d5324

Summary: Improve sexp-based movement in message-mode
Works by giving citations and smileys a different syntax. This helps
modes like `show-paren-mode', `electric-pair-mode', and C-M-*
sexp-based movement.
* lisp/gnus/message.el (message--syntax-propertize): New function.
(message-mode): Set syntax-related vars.
(message-smileys): New variable.
* test/automated/message-mode-tests.el: New file

So it's giving the first character of each cited line a "<" syntax...
