>Description:
Setting imap_delim_chars set to "/." should make these characters 
interchangeable. This does not work when renaming IMAP folders or when defining 
hooks.
>How-To-Repeat:
>Fix:
rename should s/[$imap_delim_chars]/$namespace_separator/

hook regexps should s/[$imap_delim_chars]/[$imap_delim_chars]/
so =INBOX/A would become =/INBOX[/.]A
