Go back to INBOX with next-unread-mailbox

[Nicolas KOWALSKI <niko@xxxxxxxxxxxxxxxxx>]

Hello,

I am using the next-unread-mailbox function to read my mail collection. 
For this, in my ~/.muttrc, I have defined 'c' macro like this:

folder-hook . 'bind index,pager c next-unread-mailbox'

This works well, but when there are no more mailboxes with unread mails, 
it just stay in the current folder. I would like it to make mutt "go 
back" to INBOX instead.

Any idea ?

Thanks,
