(This only applies to JOE for Windows)
When doing search/replace, replacing with "\<anything>" doesn't work. The backslash and the character after are ignored when doing the replacements.
Coupled with that other bug about ^QJ not working in the replacement prompt, it makes replacing with a new line impossible.
Thanks for the report. Indeed this does not work. The problem also appears to occur in the coroutine branch, so this looks to have been caused by a bad merge (by me).
