fix SubFolders style Maildir++
turns out i misread the spec in a subtle way: while all other folders are physically nested under INBOX, the IMAP view puts them at the same (root) level. to get them shown as subfolders of INBOX, they need to have _two_ leading dots. this also implies that the Maildir++ mode has no use for a Path, so reject attempts to specify one.
