Ah, OK, perhaps it's due to worries about interoperating with an older Emacs scheme that used just "USER@DOMAIN" without the trailing ".PID:BOOT". If so, we should use some string that cannot be interpreted as a valid domain name by an ancient Emacs. So, how about using '..' instead of ':'? That is, "USER@DOMAIN.PID..BOOT". This should work since a valid domain name cannot contain "..". The complete set of allowed characters here, if '..' doesn't work for some reason, is '(', ')', '<', '>', '[', ']', ':', ';', '@', '\', ',', '.', '"', according to Internet RFC 5322 section 3.2.3. Of these characters only '.' is allowed in a POSIX portable file name.
