It's mostly there just to make sure that ~/ or ~user/ can't be used  
to open mailboxes where you weren't supposed to have access to. I  
didn't think anyone would really want to have mailboxes beginning  
with ~. Do you really want them? (I don't think they were possible  
with UW-IMAP either?)

That's what the code does if you don't have  
mail_full_filesystem_access=yes, but I thought I'd prevent this in  
=no case just in case of a bug somewhere, possibly even outside of  
Dovecot itself.

There are too many settings already. mail_full_filesystem_access=no  
should be enough for this.
