zsh: Incorrect completions for scp & rsync

[DanielO (Daniel O'Connor)]

zsh double escapes slashes which used to be necessary for scp before it switched to the sftp protocol and rsync 3.2.4+, however now it is no longer necessary. This breaks completion on remote sites which is quite annoying. It is easily fixable by patching /opt/local/share/zsh/5.9/functions/_remote_files as per this thread: ​https://www.zsh.org/mla/workers/2024/msg00446.html

Unfortunately it looks like the request "died on the vine" upstream, I think it would be helpful to port it here.
